     Bugs fixed
+      -  As developed in a long thread starting at
+         http://mail.zope.org/pipermail/zope/2005-July/160433.html
+         there appears to be a race bug in the Microsoft Windows socket
+         implementation, rarely visible in ZEO and/or in
+         ZServer/medusa/thread/select_trigger.py when multiple processes try
+         to create an "asyncore trigger" simultaneously, most often (in
+         stress tests) manifesting as a hung process.  Windows-specific
+         trigger code in both changed to work around this bug when it occurs.
       - Collector #1844: fixed whitespace handling in the ZMI "Find" tab
       - Collector #1837: fixed full file interface support for FileUpload objects
