Comment 6 for bug 113201

hmm... i see your point, but since it is part of the PAC spec, and since it is
widely used, it would seem like a good idea to do whatever we can to make the
browser UI not hang. i don't think it would be too much work to implement, but
i also don't think it is critical enough to get high priority either. probably
this bug will just sit around for a while until someone has time to implement
it. as for the documentation approach, that should still happen. but, getting
information out to everyone is not exactly trivial either.
