Actually I found the cause and I strongly disagree with the above: The
reason the domU was blocking was because it didn't have enough memory
in the default setup. Once the memory limits were increased it worked
fine.

But the Old Maid is on xen: No matter what the issue on what
distribution I would expect some way to be able to diagnose and
identify reasons for blocking, at least to some extent.
