Hi Ian,

No strong reasons, other than to keep it very independent. There are
other users of gdbsx backend like, Maxine Inspector, which is used to
debug JAVA guests on xen. I'd think that changing it to use libxc
should be OK, since its running on dom0, and should not have any
annoying compatibility issues with gdbsx and libxc going out of sync. I
don't like interfaces changing very often, so hopefully, that would not
happen.

thanks,
Mukesh
