Hi All...

I just tried the latest snapshot (didn't expect a change, but felt obligated 
to try) with no change.

Who submitted the pipe handling code changes? Any chance of a resolution 
soon?

Where would I look to see the changes? What I mean is to look at the before 
and after?

Thanks,

...Karl
