Hugh: never mind ....


There is a workaround for this issue: use socketpair(2) instead of 
pipe(2). I haven't thought enough about the consequences yet to have an 
firm opinion on implementing os.pipe using socketpair(2) on OSX. My gut 
feeling is that we shouldn't because pipes and sockets can have slightly 
different behavior, especially w.r.t. buffering.

As a workaround for this issue you can at least use socket.socketpair 
instead of os.pipe.
