perhaps the internals of GTK/GDK has changed the ultimate ordering of
calls to the X server, so things you were doing without locks are
causing async problems. the fact that it worked under GTK+ 1.2 doesn't
mean anything - its been said over and over and over that you cannot
have multiple threads calling *any* GTK or GDK or X functions without
lock protection. if it worked before, that was just luck and relied on
the internal structure of GTK/GDK, much of which has now changed.
