The easiest, least error-prone way to do this is to use Python's Queue
module (http://docs.python.org/lib/module-Queue.html ), which was
designed for situations like this one.

Have one thread listen via WMI for Event Log entries and insert the
resulting entries with Queue.put, while another thread retrieves the
entries with Queue.get and e-mails them.  This pattern is known as producer/consumer.
