commit c632297d7b6d7267543afeb7b052dc8a970cdefe
from: Josh Rickmar <jrick@zettaport.com>

Use pipe() which is a more understood syscall than pipe2() which doesn't
exist on MacOS, for instance.  Since we we're passing in 0 to pipe2(),
this mean no fcntl() flags were being sent.  As such, it's the same
syscall as pipe() which also has the added benefit that it's more
portable.
