Bonus points for explaining > why the same scenario doesn't hang for USABLE_SIGIO platforms. 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. -- (domestic pets only, the antidote for overdose, milk.) bloggy blog: http://lars.ingebrigtsen.no
