   Question... I have heard conflicting info if (AF_UNIX, SOCK_DGRAM)
   sockets will drop packets or not. I would appreciate a conclusive
   answer for the Linux kernel specifically. Alternatively, is (AF_UNIX,
   SOCK_SEQPACKET) implemented in Linux?

If sendmsg returns no errors, we reliably send the data and
do not drop it.

We don't have AF_UNIX/SEQPACKET, but we do have AF_UNIX/STREAM.
