I'm unable to reproduce the problem at this time. Even re-installingM2Crypto
doesn't make it recur. I've been rerunning my regression test
over and over, and it's not repeatable.
I suspect that for some reason Windows networking was generating
a local error, and the Windows error status to UNIX-like error status
conversion is wrong somewhere.
