So I guess the real question is: do we want to merge the UNIX domain socket

high load seems problematic, and there are more general questions about
performance with other workloads.
Maintaining this patch for a month or so is no problem, but as the tree
changes it will get harder.
The only thing I'm afraid of is that it'll get pushed onto the back-burner
once it's in CVS, and we'll have a mad scramble to fix it when it's time for
7.0. That's not a show-stopper for it going in, as there are also numerous
benefits. It's just something that needs to be tracked and worked on.
I should be able to support/improve UNIX domain sockets moving forward without
a problem -- the maintenance issue is maintaining it in P4 indefinitely, not
in the tree indefinitely, as the patch basically touches every line in the
file, so any change in the vendor branch (FreeBSD CVS) will put the entire
file into conflict. To be specific: I'll track and own this, but want to
avoid having it in P4 indefinitely, because it will get stale :-).
