 Name: tlslite

-tlslite/TLSRecordLayer.py was changed to force the socket to be closed when the
-SSL connection is closed. This is is necessary at this point since WinHTTP does
-not seem to react to the SSL close notify.  It's also needed to prevent a hang
-on Linux.  See also 
-http://sourceforge.net/mailarchive/forum.php?thread_name=41C9B18B.2010201%40ag.com&forum_name=tlslite-users
-The change is in chromium.patch.
