Isn't this a bad idea?  SIGPIPE generally indicates that something went
wrong.  If we ignore it, important problems may go unnoticed.  To me,
this seems kind of like ignoring SIGSEGV to get around a memory access
to an unmapped area that would be inconvenient to prevent.

Furthermore, what happens if a REPL is started within a Guile process
that wants to install its own handler for SIGPIPE?

Why is a pipe being created here, anyway?  Why not just a socket?
