Why are you calling PyEval_ReleaseLock() in the CmdThread constructor?
This looks suspicious.
Also, I don't see where CmdThread::lock() and CmdThread::unlock() are

Essentially, yeah. It doesn't require (or support, depending on your

Hi,
Since the rfc822 module was removed in Python 3, and is deprecated in
2.3, I am obviously trying to avoid using it.
But I'm having a hard time finding an equivalent to rfc822.AddressList
in the email module, which I want to use to parse a _list_ of addresses:

The proper python term would be "list." You can remove all elements of

That doesn't solve the problem. You'd need locals().copy()
