Aha. I figured out the bug with closing and opening pipes (you have to do
it in the right order)!
Attached is a patch to the 121000 snapshot to get ExternalTransport and
ExternalParser to work correctly.
Please test the snapshot (pref. with patch) and push on it. I will try
fix up bugs ASAP so we can try to get 3.2.0b3 out this week. (fingers
crossed)
Cheers,
-Geoff
