[Twisted-Python] threading on windows?

[Sean Riley]

actually i have a counter question that is "how the hell does this work on
Linux at all?"

during startup, threadable.init() is called twice - once by internet.main
calling requireInit() which passes zero and once by twistd which passes zero
or one if "-t" was specified.

the first time through, the global threaded is set to zero.
the second time through, the "assert threaded is None" in threadable.init()
should always fail as threaded is not None, it is now zero. This assert
failing causes threadable.threaded to get left as zero and the
initialization of installing the waker and scheduler never gets done.

Yes, but threaded can be used without internet.main's event loop, so it
shouldn't depend on it.

note that threading has to be initialized before threadtask is imported,
so that it will be synchronized.


Can you explain why the current code doesn't work in Windows?
