> ZOOKEEPER-1702 tracks a client connection management bug.  The bug can cause an unexpected
TCP RST that ultimately prevents delivery of a session expiration event.  The symptoms of
the bug seem to show up more frequently on Windows than on other platforms (though it's not
really a Windows-specific bug).
