Which version of Python is this?  (Probably doesn't matter, but I'm
asking anyway.)  On many OSes, some calls are not thread-safe
(gethostbyname() is a common one on Unix), and threads will block until
that call returns.  You're probably hitting something like that; if so,
there's not much Python can do.
