Subject: Break reference cycle between WebSocketHandler and WebSocketProtocol on close.
X-Git-Tag: v3.1.0~113
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=3e4b4cac66308800d93509d77eb0a66fbd4cdcad;p=thirdparty%2Ftornado.git

Break reference cycle between WebSocketHandler and WebSocketProtocol on close.

This isn't strictly necessary, but it allows the refcounting CPython GC
to clean things up without waiting for a full GC.

Closes #382.
