Well, it's ugly, and probably innefficient, but it might serve
until Philip comes up with something better, so here's a patch to
src/transports/pipe.c (v2.04) ... (also describes signal names, but I
haven't tested that bit. A lot of the signals probably don't need to
be in here, and I haven't included them all. Just the more common ones
could be included)

Ugly, inefficient, and probably slow. (But it works. And that's (sort
of) what matters. <g>) I'm sure Philip will do better than I can.
