Oh fer cryin' out loud... While playing with the ypserv code on a different
platform, I discovered the following: if you use ypcat (or anything that
does a yp_all() for that matter) to dump out a map and then hit ^C before
it finishes, ypserv gets hit with a SIGPIPE and dies. (The ypall() service
is implemented using TCP.)
Fix: ignore SIGPIPEs.
