3998 | clean way to handle the situation where a deferred message is | |
3999 | "dropped" in the lisp thread, and will thus never be | |
4000 | completed, eg. by the user trying to activate the menubar | |
4001 | when the lisp thread is busy, and then typing C-g when the | |
4002 | menubar doesn't open promptly (with the result that the | |
4003 | menubar never responds at all because the deferred | |
4004 | WM_INITMENU message is never completed). Another problem | |
4005 | situation is when the lisp thread calls SendMessage (to send | |
4006 | a window manager command) when a message has been deferred; | |
4007 | the lisp thread gets blocked indefinitely waiting for the | |
4008 | deferred message to be completed, which itself is waiting for | |
4009 | the lisp thread to respond. | |
4010 | ||
4011 | Note that we don't want to block the input thread waiting for | |
4012 | a reponse from the lisp thread (although that would at least | |
4013 | solve the deadlock problem above), because we want to be able | |
4014 | to receive C-g to interrupt the lisp thread. */ | |
