While I think this whole "xid" thing is a bogus idea, if we're going to
do it, we should at least try to be consistent about the type. _GetXid
returns unsigned int but you're turning that into a signed int here.
I suggest that we don't do that. Let's declare henceforth that it's
unsigned. Any place that treats it as signed is a bug. We probably have
a lot of these bugs. I don't expect you to fix them all up, but you
should at least try to fix that up in the code that you're touching in
this series. We can get the rest later...
Sound ok?
