Cocoa, httplib and threads?

I'm trying to use httplib to send an http request in
a background thread. It works fine on its own, but when
I do it inside a Cocoa application, the thread hangs
as soon as it tries to send the request.

It doesn't seem to be a GIL problem, because I can do
other things in the thread leading up to that point.
It's just sending the request that seems to block.

Is there anything I should be aware of when using
the threading module in conjunction with pyobjc?
