That doesn't sound very good.
There's nothing wrong (fundamentally) with the UNBLOCK_INPUT causing
another call to XTread_socket: after all, we've basically finished the
first call when we get to UNBLOCK_INPUT, so there's no "nested
interrupt" problem, AFAICT.  After all, we're just coming out of
a "while (gtk_events_pending ())", so the case where we get "called
recursively" should be very rare.

I.e. I think this "problem" can only happen in bogus cases such as with
Gtk's bug.
