Temporarily back out kern_sig.c rev 1.125 and kern_exit.c rev 1.131.
This paniced my one of my machines one time too many :-( and there is
no sign of a solution in the pipeline. The deltas are still easily
available in cvs. The problem is that if the parent has been swapped
out, the child process cannot grope around in the parent's UPAGES to
see the sigact[] array or it will fault. This probably is a showstopper
for this implementation anyway.
