Cool. (I know the FreeBSD folk have a pretty large set
of user-mode emulation changes which we've unfortunately
not been able to get upstream yet since there's a lot of
cleanup work required.)

Does the user-emulation work for running random
binaries, or are there known limitations to what
guest/host architectures work well? (I have some
BSD VMs which I was using for compile testing of
the bsd-user code a while back, but I forget what
results I was seeing with which BSD variant...)

If they're small you might as well post them here anyway;
we may be able to suggest a better fix or perhaps they'll
be OK to apply upstream anyway.
