I haven't checked the RFC, but I don't believe the Expect header has
anything to do with 100-continue.  There is nothing unusual about a
server sending a 100 continue response for a POST.

You haven't mentioned which version of Python you're using, but it
probably doesn't matter.  I think all released versions of Python have
an httplib that does not handle 100 continue responses.  The code has
been fixed and will be available as soon as 2.2.2 and 2.3 are
released.  Until then, you may want to grab the latest source from CVS
and see if that helps.
