Well, this is a pretty bad side effect of running ORBit, it should be
at least documented.

And I do *think* that you do not get SIGPIPE the first time you write
to a dead socket, you get it the second time.  The first time you get
some meaningful error.

Now, an alternative approach is to make SIGPIPE point to a signal
handler (this way it will get reset over forks).  The signal handler
will just make write return EPIPE on failure.
