On the libevent list, there's a thread on this, with a proposed
libevent patch from Scott Lamb.

  The thread is here:
  The patch is here:

If you're running svn Tor (especially on BSD or OSX), and you've been
seeing SIGPIPE errors or other weird signal messages, it would be cool
to know whether this patch to libevent helps anything for you.
Conversely, it would also be good to know whether this patch breaks
stuff horribly for you no matter what you're running.
