SocketServer shutdown deadlock

[Okko Willeboordse]

All,

With Python 2.5 SocketServer features the shutdown method that can be
called from another thread to stop the serve_forever loop.

However;

When the shutdown method is called before serve_forever, shutdown will
never return.
This can happen when a server is stopped during startup.

In other words, the following program shouldn't hang but it does;

import SocketServer

server = SocketServer.ThreadingTCPServer(("127.0.0.1", 12345),
SocketServer.BaseRequestHandler)
server.shutdown()

What to do?

If I wait until _BaseServer__serving is True before calling shutdown
things go better.
