It's hanging here:

x_get_foreign_selection (Lisp_Object selection_symbol, Lisp_Object target_type,
			 Lisp_Object time_stamp, Lisp_Object frame)
{
[...]
  wait_reading_process_output (secs, nsecs, 0, false,
			       reading_selection_reply, NULL, 0);

That is, it's not really hanging hanging, but this sometimes takes a
couple of seconds without SIGIO, while it returns instantaneously with
SIGOI.
