Subject: [PATCH] two changes:   1) try to fix a problem on FreeBSD where it
 seems the parent process is      not waiting for the child (piped) processes
 to complete.   2) handle the checkout_magic_path better -- it was showing up
 as the      request.module and getting caught up in the 'forbidden'
 processing.
