Conversely, does a unstable-built UML run on woody?

Only those, or are there others that you can tell are failing? Offhand, I
don't see any commonality between those three, in terms of their interactions
with the host.

The randomness is strange. It suggests that somehow interrupts are getting
in the way. One possibility would be host system calls returning ENOSYS
instead of EINTR. I don't see much possibility that that's what's actually
happening, but that's the sort of thing I'd think about.
