`J' flag means that newsyslog should wait for previously started compression
jobs to complete before starting a new one for this entry. When it is used
along with the `G' flag, in the case when several logfiles match the pattern
and should be compressed, the newsyslog will compress logs one by one,
ensuring that only one compression job is running at a time.
This prevents newsyslog(8) from overloading system by starting several
compression jobs on big files simultaneously.

resource starvation we clean-up as much of the vmspace structure as we
can when the last process using it exits. The rest of the structure
is cleaned up when it is reaped. But since exit1() decrements the ref
count it is possible for a double-free to occur if someone else, such as
the process swapout code, references and then dereferences the structure.
Additionally, the final cleanup of the structure should not occur until
the last process referencing it is reaped.
This commit solves the problem by introducing a secondary reference count,
calling 'vm_exitingcnt'. The normal reference count is decremented on exit
and vm_exitingcnt is incremented. vm_exitingcnt is decremented when the
process is reaped. When both vm_exitingcnt and vm_refcnt are 0, the
structure is freed for real.

make it easier to find how `interactive merging' works with sdiff.

this doesn't work quite right with our groff. They have an older
groff version in the base system, but no real plans to update both
groff and manpages. Fix the .Nm usage locally in our manpages.

Hold the page queues lock when calling pmap_unwire_pte_hold() or
pmap_remove_pte(). Use vm_page_sleep_if_busy() in
_pmap_unwire_pte_hold() so that the page queues lock is released
when sleeping.
it possible to make UFS1_ONLY and UFS2_ONLY versions which fit inside the
traditional 16 sectors.
Remove assorted now unneeded hackery.
UFS1_AND_UFS2 still needs another 150 bytes to work, and that is probably
not within our reach, ever.
Reimplement the necessary bits from auth_pam.c and auth2_pam.c so that
they share the PAM context used by the keyboard-interactive thread. If
a child process is used instead, they will (necessarily) use a separate
context.
Constify do_pam_account() and do_pam_session().
