It is obvious, that `file-notify--test-with-events' isn't kosher. No
event arrived inside this macro. The stopped event arrived later, in one
of the unwindforms of the surrounding unwind-protect.

Are there special problems with cygwin Emacs related to the
`with-timeout' macro?

Hard to debug, because we are faced with timing issues. So I would need
to do this myself ...

Well, I'll try to find a machine where I could install cygwin. Where
could I find a very recent Emacs, including the patch of gfilenotify.c
I've committed yesterday?
