According to the author..

"I've been having a problem running the patches [committed to current]
installed with the COMPAT_LINUX_THREADS option along
with the VM_STACK patches I did.  I'm not sure what
the problem is, since it seemed to work before.

In any event, the attached patch fixes the problem for
me.  While I've had no report of problems from anyone
else, possibly it would be wise to commit the patch
until the problem is found.

Also, there was some left-over junk in the linux_misc.c
file from some earlier work I did.  The attached patch
cleans that up too."
