Yes, I've found the problem just after (unfortunately) having posted my
previous message: the socket module, used by httplib which is itself used
by urllib, is not a pure python module, but a C module. 

I knew the problem because I had to deal with it before.

I'm currently downloading the python source tarball to look at the socket
module to know if I can use threads or if they are blocked during the
connect the same way that signals are. 

thanks for the help, I'll try to post a new version today.

bye,
