Thanks, this looks good.

This could become a one-liner:

  return socket(AF_UNIX, SOCK_STREAM, 0);

to keep the details abstracted. But it's local to this file, the callers
are already necessarily full of bsd-socket arcana, and it's not like the
magic words there have ever changed in 30+ years. Putting it inline
seems quite reasonable. :)
