Hmmm, I don't know if I believe that. > I looked at another set of bindings for FAM in Java. > It came with an example that watched a directory for changes.

You call is probably doing a select(...) on the file handle that FAM (or whatever) is going to call back on. You could probably override that method and add a timeout. Then do-whatever... wait-and-listen... do-whatever. This works very well in many cases, you won't loose events, they will still be there when you go back to check. > I don't know how to do something like this in Python, I have never > used threads and I'm not sure if thats the way to go. In Python I'd use multiprocessing rather than threads. <http://docs.python.org/library/multiprocessing.html> -- OpenGroupware developer: awill...@whitemice.org <http://whitemiceconsulting.blogspot.com/> OpenGroupare & Cyrus IMAPd documenation @ <http://docs.opengroupware.org/Members/whitemice/wmogag/file_view> -- http://mail.python.org/mailman/listinfo/python-list
