BSD systems tend to claim SOMAXCONN = 5 in the header files, but *not*
to have such a small limit in the kernel.  The real step forward that
we have made in this discussion is to realize that we cannot trust
<sys/socket.h> to tell us what the kernel limit actually is.

It demonstrably is not sufficient.  Set it that way in pqcomm.c
and run the parallel regression tests.  Watch them fail.
