yep.  although i just realized that what i was thinking probably won't work
with the proposed X11 shared memory extensions since the zlogin process
would be acting as a relay, and hence a getpeercred() issued by the
Xserver would return info for the zlogin process and not the X11
application.  not sure how to fix that...  somehow we'd actually need
to get the pipe in the global zone connected to the one in the local
zone...  hm.
