Unfortunately, I was pretty groggy (just gotten out of bed) when I noticed, so
I made a few major mistakes (like not writing down the panic message).  I did
type trace, and noticed that at least half of the function names that showed
up had 'soft' in the name.

No partition has 'async' or 'noatime' specified.  Everthing but '/' has
softupdates.  (some are mounted with some combination of nodev/nosuid/noexec).
DEVFS and SLICE are absent.

It happened during the installworld part of a make world (actually, installing
awk at the time).  It ate quite a few files (probably the last 20 written or
so) from /usr, but none that mattered for 'make installworld' (fortunately).

I will try to reproduce this, but it may take awhile (this is a amd486-133).
Although, 'make world' takes ~6 hours now (based on the timestamp on
/usr/obj/lkm/wcd/wcd_mod.o 4:31 -> 10:26).  It used to take ~8 hours without
softupdates.  That's just a normal 'make world' with no 'NO***' options, and a
clean /fs/scratch (erm...  /usr/obj).  installworld takes ~6-7 minutes.

[ damned, that's only ~2.5 times longer than my wimpy little k6-233 w/o
softupdates ]

Real Programs don't use shared text.  Otherwise, how can they use
functions for scratch space after they are finished calling them?
