> It's not that the NS pselect waits too long. It's that it doesn't know to wake up. The focus event is delivered to Emacs by NS as a callback. Unless that callback, one way or another, takes some action to wake up the event loop, nothing gets processed. On Windows, we drain the event queue as a side effect of the message pump, whereas on NS there doesn't seem to be a separate pump that works this way -- just a callback.
What about making pselect wait on one more descriptor, to which the
callback could then write?
