Chad Brown reported a very specific issue exactly like the one I experienced, with the symptom being that keypresses are handled very slowly, but he couldn't debug it further because Emacs crashed. Mitsuharu commented in the thread: > As multi-tty no longer does `FD_SET (0, &input_wait_mask)' in > process.c, if no `add_keyboard_wait_descriptor' calls are made, then > Carbon Emacs reads events from the window system only rarely via > polling with SIGALRM and becomes very unresponsive as reported. Mitsuharu, can you tell us if you think this problem can be solved easily? Regardless of the state of the Carbon/Cocoa/etc ports, I'd like to have something that works in the CVS Emacs for MacOS users. Can we just reintroduce that FD_SET call, or will that break other things? Should we increase the frequency of the SIGALRM polling instead? If Karoly Lorentey is around, maybe we can get their comments as well. Thanks Ted
