not per-process. Keep it in `switchtime' consistently.
It is now clear that the timestamp is always valid in fork_trampoline()
except when the child is running on a previously idle cpu, which
can only happen if there are multiple cpus, so don't check or set
the timestamp in fork_trampoline except in the (i386) SMP case.
Just remove the alpha code for setting it unconditionally, since
there is no SMP case for alpha and the code had rotted.

To prevent a deadlock, if we are extremely low on memory, force synchronous
operation by the VOP_PUTPAGES in vnode_pager_putpages.
to calculate a reasonable size for the swap partition).
* Fix a typo in remrq() where a process with idle priority would not be
correctly removed from the relavent queue. Note that realtime and idle
priorities are still not supported since the assembler code in
cpu_switch() does not check the realtime and idle queues.
- Transparent proxying support added.
- PPTP redirecting support added based on patches

that are made in each of the FSMs (LCP, CCP & IPCP) and the
number of REQs/Challenges for PAP/CHAP by accepting more arguments
in the ``set {c,ip,l}cpretry'' and ``set {ch,p}apretry'' commands.
Change the non-convergence thresholds to 3 times the number of configured
REQ tries (rather than the previous fixed ``10''). We now notice
repeated NAKs and REJs rather than just REQs.
Don't suggest that CHAP 0x05 isn't supported when it's not configured.
Fix some bugs that expose themselves with smaller numbers of retries:
o Handle instantaneous disconnects (set device /dev/null) correctly
by stopping all fsm timers in fsm2initial.
o Don't forget to uu_unlock() devices that are files but are not
ttys (set device /dev/zero).
Fix a *HORRENDOUS* bug in RFC1661 (already fixed for an Open event in state
``Closed''):
According to the state transition table, a RCR+ or RCR- received in
the ``Stopped'' state are supposed to InitRestartCounter, SendConfigReq
and SendConfig{Ack,Nak}. However, in ``Stopped'', we haven't yet
done a TLS (or the last thing we did is a TLF). We must therefore
do the TLS at this point !
This was never noticed before because LCP and CCP used not use
LayerStart() for anything interesting, and IPCP tends to go into
Stopped then get a Down because of an LCP RTR rather than getting a
RCR again.
drive has very poor write performance (1.4MB/sec vs. 12MB/sec) with anything
more than two oustanding transactions.
So, this limits the number of tagged commands to two for that drive.
Thanks to Paul van der Zwan for doing a whole lot of testing to confirm
this.

correct drive number by the PC BIOS. (The symptoms are a
"F5 Drive 0" line, even though the current drive is drive 0.)
Specifically, the test was in the wrong place, lacked a cast, didn't
unlock the node, and exited to bad rather than abortit. Now we don't
allow renaming of a file with LINK_MAX references. Move the test to
earlier in the code as it is closer to where ip is obtained, as that
is the style of the rest of the function.
Didn't fix the problems bruce pointed out in the rename man page to
include EMLINK, nor address his complaints about how the whole idea of
incrementing the link count during a rename is potentially asking for
trouble.
Also didn't try to correct potential problem Terry pointed out with
decrements not being similarly protected against underflow.
