we seem pretty solid on ia32
^Z and then fg will sometimes kill teh process instead of forgrounding it
though.
(I aborted several buildworlds that way accidentally)
Andrew's panic seems SMP specific though..
you may check if there is somethign different between ia32 and alpha
on whether it holds schedlock at this point:
panic: mutex sched lock not owned at ../../../kern/subr_smp.c:126
cpuid = 1; lapic.id = 01000000

I'm trying to test jeff's latest patch but got side tracked by hardware ..
