I suspect it might be due to interaction with the window-manager.
You'll probably have to use a gdb to see where in the code Emacs is looping.
Note that if it indeed has to do with the window-manager, you'll need to be
extra careful when debugging: ideally, run the debugger on another screen.

Back in Emacs-21 pretesting, I remember seeing something that sounds very
similar where ediff would freeze and the code was looping around some
set-frame-parameter stuff (something like: set-frame-parameter caused
a message to be sent to the window-manager which was replying with another
message which in turn cause a new call to set-frame-parameter, ...).

Of course, your problem might be completely different.
