I hacked this patch into the vm/vm_pageout.c source of a NetBSD/sparc 1.1
kernel, knowing this was probably a very bad idea. So, I'm not criticizing
Mr Stone. I'd just like to ask about a weird anomaly that seemingly arose
from this patch.
The kernel with the modified calls to tsleep() in vm/vm_pageout.c caused
twm to coredump with a bus error most of the time.
Two different twms coredumped: the one from the Sept 15th, 1995 binary
X11R6 distribution that used to be on one of the NetBSD ftp sites.
The 2nd twm, I recompiled from X11R6pl12 sources using the Princeton/Bell
Labs lcc-3.5 compiler. I've been using both twm executables for a while
now, and I've never noticed anything odd from them.
Nothing else seemed to have troubles.
