There are more details in the code regarding how to use this feature.
Also shift a few of the orte_output back to opal_output. I'm experiencing an odd problem with locks in the oob/tcp when using orte_output. I haven't had time to track it down yet.

Any components not in the trunk, but in one of the effected frameworks *must* be
updated. Contact the list, look at the RFC, or look at the diff for how to do this.

numbers for tuning.
Switch the bookmark_recv to be non-blocking. If this is blocking then for
process counts >= 32 slight process delays were causing cascading performance
delays in the protocol. This lead to checkpoints either taking about 3 sec or
45 sec (or more) for 64 procs due to the cascading delays. With the nonblocking
receive version this is no longer the case we get the speedup we expect for this
part of the protocol.
More tuning to come.

It's a bit longer, but much more clear in it's implementation I believe.
Fundamentally it is the same, but is much more solid in the implementation.
I created quite a few directed tests that this version of the implementation
