Yup, but you must somehow communicate with the master process, and this
is currently missing from the lguest implementation since everything is
shared (vm + fds).

If you simply unshare it, you must have a different method of talking
with the master process. I suggested doing it using unix sockets, and am
wondering how Rusty did it in his patch.
