I don't quite see how that can happen. Xdebug will make a connection for
*every* request (not just once in a multi-request script) so I don't see
how you can have a blocking socket. Perhaps you have a blocking accept()
though but that shouldn't be a problem as that shouldn't block any other
communications.

I don't want to create an option for this, as Xdebug has too many
options already in my opinion.
