I fixed this previously, but IIRC we had to back out my fix due to a horrible
bug in XenD. It was something like XenD would leak the socket into the QEMU
device model, so if you did a big 8000 byte read we'd just block waiting on
end of file which never came. Any Xen 3.0.3 or newer has a fix.

We could probably re-instate my original fix 

    cvs diff -r 1.18 -r 1.19 -up xend_internal.c

Perhaps making the code conditional on xend_config_version >= 2 to avoid
tickling the bugon 3.0.2
