Perhaps somebody can tell me what the problem was which the check-in
from 2002-02-22 was supposed to solve in order for me being able to
check if this is still an issue. I could not find anything related to
it in the list archives of emacs-devel or emacs-pretest-bug (the
archives of which only start in December 2002).
There was a resource leak when popup menus were cancelled (by pressing
ESC) without selecting any option.
To fix this, I initially tried freeing the resources when the
WM_EXITMENULOOP message was received, but this was too early for the
case where a menu action was selected, since the Lisp code was still
dealing with the selection at that point.
It might be possible to fix this with careful use of synchronization
between the Lisp thread and the message loop, but there is already some
synchronous message passing in the menu code I think, so deadlocks may
be difficult to avoid.
