My 3.1 testing has revealed a problem when rapidly rebooting a single
domU. Eventually, xend gets a wrong type response in xs.c (it's
expecting a reply to XS_READ, and it gets a reply to
XS_TRANSACTION_END). This breaks everything horribly, as xend is very
poor at recovering from an error like this.

I'm still looking at it, but I wonder if people are doing a similar test
and if anyone else has ever seen it. The classic symptom is something
like:

# xm list
Error: (2, 'No such file or directory')
Usage: xm list [options] [Domain, ...]

Or more often EBADF
