This is silly. It can't possibly work right since there is no reason
that messages are sent using the exported functions, it won't work on
anything not compiled with frame pointer, and there's absolutely no
need for anything like that at all. A posted message doesn't call the
window proc directly, it goes through the message queue, so it's
completely trivial to check for it between GetMessage and
DispatchMessage.
