If you mean the OS poll() function, X.org has historically had a bug
(in true X.org fashion, they say it's not their job to keep promises
if other software might be buggy) where _XtWaitForSomething() can
infloop in non-blocking mode.  I forget whether this shows up with
poll() or with select().

It's not an infinite wait.  It's Emacs blocking on *any* input.  The
function should return as soon as there's input.

I would check for a bug like the above in GTK.
