Comment 23 for bug 1682411

Here is an alternative that sets umask before creating the file. I would have thought that since we aren't accepting anything on the socket it would have been ok, but this should still prevent us from creating the file with the wrong mode, correct?

I wasn't able to find a trivial way to 'mksock' with the right parameters and get that passed into a net.Listener (I believe you can open them from a file descriptor, but I didn't see a mksock function).
