2nd version of demo program showing how wine cheats

This is a guess, but:
Wine's implementation of change notification
seems to have taken a gamble.  If you insert a
 dir /s 
after calling ReadDirectoryChanges the first time,
it works.  Why?  Because server/change.c probably bets
that the app would do a recursive scan of the
watched directories after issuing the first ReadDirectoryChanges,
and piggybacks on that scan to do all the needed
inotify_add_watches.

The fix is probably for Wine to do its own 
darned recursive scan, hang the overhead.  
Alternately, affected apps (like Picasa) could make sure they 
start their recursive scans *after* calling ReadDirectoryChanges.
