Ok I now made a -current qemu -smp 2 guest and did
	cpuset -l 1 zsh
and in that shell ran qemu-system-x86_64 with kqemu on the 7.0 livefs iso,
and I could enter fixit without a crash!  Tried the same for cpu 0
	cpuset -l 0 zsh
and got a crash again.  Can anyone reproduce this on a physical box,
and possibly test other guests, and/or hosts with more than two cpus?
(Linux guests for some reason didn't want to work for me in qemu in qemu...)

 Thanx,
