My understanding is Application.ProcessMessages has to be reentrant
for the clipboard to work, at least under X, as clipboard content is
retrieved by receiving messages. See
http://bugs.freepascal.org/view.php?id=26242 for a (fixed) bug that
showed this up. The sequence is something along the lines of (for
example) ProcessMessages -> Handle paste button -> clipboard ->
ProcessMessages.
Well, in general it appears to behave, otherwise a lot of code would fail.
I just stumbled in a special case, when Application.ProcessMessages is
called from within the handler of a message posted by a PostMessage from
a different thread. It would appear that, under some circumstances
(because the error appears randomly), there's a bug which causes it to
pass again the same message, thus causing and endless loop. It's the
recursion in this specific case which appears to be buggy.
