Somebody should make a mib variable for it.
Just now it is pointless to dump the kernel, since we have nothing which
can read the dump.
Furthermore is should never be the default to dump.

profiling and wchar_t. Profiled libraries will shrink.
tm.h:
Our wchar_t is int, not unsigned short.
Always link statically if profiling.
Define all the SPECs together.
final.c, tm.h:
Don't emit unused profiling code and data.
aux-output.c:
Always preserve the PIC register if profiling.
aux-output.c, tm.h:
Implement FUNCTION_PROFILER_EPILOGUE (currently not used).

Set the target defaults in the correct way.
there is an extra target now for creating a 1.2MB floppy at the cost
of a few of the doc files. Just do a `make small.floppies' instead of
a `make floppies' to make a small set.
When we get an EN8 response while we're already sending the file using
the i protocol, this can happen:
In send.c, flocal_send_await_reply() is called. This function calls
flocal_send_fail() to process the aborted transfer. After this, we run
into the branch that calls ffileseekend() to force the end of the
actual transfer.
Now flocal_send_fail() frees qtrans, but qtrans is still used later!
I propose to fix this by moving the usfree_send(qtrans) out of
flocal_send_fail(), as in the patch I append to this mail.
...
I have found a race condition in the uucp 1.05 code. The typical result
is that the connections mysteriously fails with "conversation failed",
even while all files were transmitted. This is the problem:
At least for the i protocol, the code to send a packet can receive and
process packets after sending.
In several places in the code, we send a command and then prepare to
receive an answer.
Now the answer might already arrive during the call that sends the
command while we aren't ready to process it.
The general solution is IMHO first to do all preparations and only as a
last step to send out the command.

MKINIT line that doesn't have a comment on it (we have at least two).
This mkinit program was written by someone who obviously doesn't believe
in defensive programming. :-( There's a LOT of work that needs to be done
on this thing. :-( :-( :-(
Enabled via REL2_1.
Added support for doing object collapses "on the fly". Enabled via REL2_1a.
Improved object collapses so that they can happen in more cases. Improved
sensing of modified pages to fix an apparant race condition and improve
clustered pageout opportunities. Fixed an "oops" with not restarting page
scan after a potential block in vm_pageout_clean() (not doing this can result
in strange behavior in some cases).

2. Install the very first cut of my bininst stage6 script. VERY rough,
it doesn't actually do anything just yet, but I need to make sure that
it's at least executed for the moment.
main.c sanitize the logic of what we do when:
if(getpid()!=1) do stage0 & stage1 (very useful actually)
else if (floppy-marker-file is there) stage0-2, reboot
else stage3-5

conversions in hzto() (division by (tick / 1000) == 0). This was
fixed in 1.1.5.
Eliminate some extern declarations by including the appropriate header

my limited alternatives: I can't make this an execvp() without making
people scream that I introduced a failure point or slowed down pwd,

arbitrary command-line args to the build of one of its crunch-ees.
This is the simplest, if not the nicest looking, solution I could come up
with.
tsleep()). Try `dd if=/dev/zero of=/dev/pcaudio bs=640k count=1'. The
write takes a few hundred seconds to drain, and if it is killed by a
signal, it still takes a few hundred seconds to drain and all of those
seconds are spent busy-waiting.
Clean up includes and declarations. Remove bogus casts of args to

doesn't have to calculate it every call.
Rename `timer0_prescale' to `timer0_prescaler_count' and maintain it
correctly. Previously we lost a few 8253 cycles for every "prescaled"
clock interrupt, and the lossage grows rapidly at 16 KHz. Now we
only lose a few cycles for every standard clock interrupt.
Rename `*_divisor' to `*_max_count'.
Do the calculation of TIMER_DIV(rate) only once instead of 3 times each
time the rate is changed.
Don't allow preposterously large interrupt rates. Bug fixes elsewhere
should allow the system to survive rates that saturate the system, however.
Clean up declarations.
Include <machine/clock.h> to check our own declarations.

Make it work with 2.0. It wasn't designed to be called at splclock().
Make it work with prescaling. The overflow threshold was bogus.
Make it work for any HZ. Side effect of fixing prescaling.
Speed it up. Allocate registers better. Reduce multiplication and
division to multiplication and a shift. Speed is now 5-6 usec on a
486DX/33, was about 3 usec more.
Optimize for the non-pentium case. The pentium code got moved around
a bit and hasn't been tested.
Change #include's to 2.0 style.
