Log Message:
Pull up revision 1.29 (requested by chs in ticket #777):
PR/25699: David Laight: sh(1) hangs opening a named pipe as stdin for
background process
This happens because we vfork, and then open a named pipe with O_RDONLY
and block in the child. We avoid this, by opening the file with O_NONBLOCK,
and then reset it if we are vforked. XXX: this is an ugly fix.
