This isn't thread safe. Changing signals with sigaction affects the
entire process - so if you've got multiple threads running with
multiple  remote connections open, you can get overlapping calls.
Either we should just block sigpipe in virInitialize, or mandate
that the application needs to block sigpipe itself. I'm not sure
really what best course is - I'd probably lean towards saying it is
the application's responsibility to deal with sig handlers.

Regards,
Dan.
