This is fixed, to a degree, with r25659. However, note that there is one big change that occurred back when we first committed the mapping change.

As I noted at that time, we changed the default for RM-given allocations to be no-oversubscribe. So your MTTs may well fail if they weren't updated as all those tests oversubscribe the nodes, and are running in RM environments.

Last night MTT test results for 1.7a1r25652 from IU and Oracle is showing failures during some of the spawn tests see http://www.open-mpi.org/mtt/index.php?do_redir=2036.

Essentially, the test are failing with the message:

All nodes which are allocated for this job are already filled.

I wonder if this is related to some of the hostfile changes done lately.  Anyways, I am 
working on narrowing down the revision that introduced that but if someone figures this out 
before me that would be great.
