Revision 56905

Got a really nasty problem with the parser where we were getting an ugly 
"Read end Dead" exception because of some nasty hacks in the Piped streams
specifically to handle and deal with two threads reading.  We do not have 
this issue since we use the dangerous case where a single thread does both
:) but for our case its ok and it works just fine without deadlocks: or 
at least we think.
