I still haven't heard from anyone about whether or not the following
changes are the only ones necessary to pull this fix up in its entirety
to the netbsd-4 branch....

My system has now been running a wrstuden-fixsa kernel with an
outstanding uptime of 16 days. Today for the first time some gzcat
processes _temporarily_ got stuck in the vmmapva state in the same way
as I originally reported when opening this PR.
At that time sysctl vm.bufmem was showing over 300 MB allocated, and
vmstat -m was showing a utilization of just over 82%.
However somehow things got unstuck and now I see vm.bufmem and the
"utilization" reported by vmstat -m both steadily decline over a period
of many minutes.
Note in particular the "Fail" column in the "Memory resource pool
statistics" of the current "vmstat -m" output below. Those numbers for
buf*k increased while the gzcat processes where stuck but haven't
increased since.
Two things about all of this stand out to me:
1. Each time that I've seen the problem happen while I've been using the
system there was some involvement of NFS mounts (and though the
nightly cron jobs do their best to avoid accessing NFS filesystems,
there's no doubt they do at least some NFS operations).
2. Sometimes the problem clears itself up within a few minutes.
Sometimes it doesn't even after many hours. However since running
the wrstuden-fixsa kernel the system has only locked up "permanently"
once and this past 16 days uptime is the longest it has enjoyed in
many months.
I think there's probably some combination of problems causing the
lockup. One is perhaps the over-utilization of kva, and the other is
that sometimes whatever needs to run to free available kva doesn't get a
chance. I don't know if the wrstuden-fixsa changes are responsible, or
if it's just a pure co-incidence. However if the past patterns of
things getting slowly wedged repeat themselves (especially with the
nightly cron jobs) then that might suggest the wrstuden-fixsa changes
have no effect and that it's simply a matter of kva sometimes running
out so completely that even whatever threads could run to free some
space are unable to run. In any case I think it would be very wise to
do something better to assure that bufmem and other cache allocations
don't jeopardize the system under the default configuration.
