Perhaps some older BSD's don't have IPC message queues ???

If you want to look at some of the changes I made, I put a little
tarball at http://www.jps.net/egm2/sockets.tar.gz.  This has the major
files modified (SWITCHER.c, io.c, unix_socks.c [new]).  It's by no means
a plug-in, since there were a lot of little other tweaks (like to d.mon,
for instance, to change calling convention for XDRIVER).  Generally, I
think it's a bit cleaner (just a bit, though), but I'm biased ;)
