BTW, the fix didn't occur over the weekend because of some merging
issues.

I also didn't explain the problem well; you may see some clipped
output from your program or the orted may hang while everything is
shutting down. This is especially likely to occur for very short
applications.

The problem is actually in the oob; the orted gets into a state where
it's waiting for some IOF OOB callbacks to occur for messages that
were already successfully sent, but the callbacks never occur due
to... well, it's a long story. The IOF is basically spinning during
the orted shutdown waiting for pending OOB callbacks that will never
occur.

I can explain in more detail if anyone cares, but hopefully Brian
will be able to work the fix in within the next few days.
