try this:
in tdsignal, (kern_sig.c) take a lock on schedlock and release it again, just around the call to forward-signal()
forward_signal(c4445540) at forward_signal+0x1a tdsignal(c4445540,2,2) at tdsignal+0x182 psignal(c443d558,2) at psignal+0x3c8
hopefully this will not be called with the schedlock already locked
if we panic becasue we already own it, it gets more difficult..

An easy way to induce a panic w/a post KSE -current is to ^C gdb as it starts on an SMP machine:
A possibly related breakage is:
type ^Z while doing "make buiildworld" (or something similar).
when you type 'fg' there is a high change the build will abort..
This is nearly 100% for me. But only on MP boxes. On my uniprocessor alpha, things work just fine. Oh.. hmm.. I'm not sure if I have witless compiled in there..
which is almost 100%,? the ^Z killing the process, or ^C killing the machine?
^C killing the machine.
