        This code is not maintained, does not work properly, and no-one is
        using it.  Delete it, following discussion on xen-devel.

and has now been replaced with gdbsx.

We are having trouble tracking down all of the contributors to the
ptrace code in libxc (as part of the effort to relicense libxc under the
LGPL, see [0] or [1]) and if this functionality is no longer required it
would be simplest to remove it. I will follow up shortly with a patch to
disable the build by default and the code will be removed shortly unless
anyone objects. If you have an out-of-tree project which is using this
functionality (specifically the functions xc_register_event_handler()
xc_ptrace() and xc_waitdomain()) then please tell us ASAP.
