Actually, I was not talking about the recursive-entry problem here. I 
was referring to our symlink-handling implementation. The first version 
of our symlink-patch caused two ON_CLOSE events to be sent from driver 
to daemon, one where the file was the symlink and one where the file was 
the real file.

Later we modified our symlink-patch so that symlink access was reported 
as an ON_LINK event and the real file reported as an ON_OPEN event.

Anyway, I will send you the patch. Code speaks clearer that words. Or at 
least my words...
