dolock is not set (that is, targetvp == overlaying vnode object).
Current code use FIXUP macro to do this, and never unlocks overlaying
vnode object in union_fsync. So, the vnode object will be locked
twice and never unlocked.

relookup() in union_relookup() is succeeded. However, if relookup()
returns non-zero value, that is relookup fails, VOP_MKDIR is never
called (c.f. union_mkshadow). Thus, pathname buffer is never FREEed.

allow large systems to boot successfully with bounce buffers compiled
in. We are now limiting bounce space to 512K. The 8MB allocated for
a 512MB system is very bogus -- and that is now fixed.
the pv entries. This problem has become obvious due to the increase
in the size of the pv entries. We need to create a more intelligent
policy for pv entry management eventually.

more often than necessary since pages were not put on the
cache queue, when they should have been.

fork. (On my machine, fork is about 240usecs, vfork is 78usecs.)
Implement rfork(!RFPROC !RFMEM), which allows a thread to divorce its memory
from the other threads of a group.
Implement rfork(!RFPROC RFCFDG), which closes all file descriptors, eliminating
possible existing shares with other threads/processes.
Implement rfork(!RFPROC RFFDG), which divorces the file descriptors for a
thread from the rest of the group.
Fix the case where a thread does an exec. It is almost nonsense for a thread
to modify the other threads address space by an exec, so we
now automatically divorce the address space before modifying it.

to have pre-allocated IP numbers while others get

Document this behaviour. Document that the number of dial attempts
applies to the number of phone calls rather than the number of times
each number is dialed. Add a missing .El. Give a decent description
of how to connect to an ISP.

Also mention the `gdb' and `help' commands. Other commands need an
overhaul, too (like the various `show' subcommands), but i don't feel
very competent for these.
the src/contrib/tcl directory existing, and also have an /etc/make.conf
override (NOTCL) to stop building libtcl. This is in similar other
things from src/Makefile, eg: NOGAMES, NOLKM, etc.
This is so that people can put in a refuse entry in their cvsup files and
not fetch the tcl code, and have it not built automatically. I'll do
something similar for perl.
- don't quote function names, since quoting them is unnecessary and
unusual and confuses my synopsis checker.
- include <sys/types.h> instead of <sys/param.h>. It is normal to
(have to) include <sys/param.h> instead of <sys/types.h>, but it
is more useful for man pages to document minimal prerequisites.
- don't declare nonexistent function sleep().
- don't include <sys/errno.h> explicitly.
sleep() should be nuked some more, e.g., this man page should not be
named after a nonexistent function.
dependency on `bar' is very unlikely to be correct.
This is a quick fix for broken dependencies in gdb and many other
places. The dependencies on internal libraries are now missing
instead of wrong when `make depend' is run before the libraries
are created.
