[MTT devel] Tracking process stats

[Josh Hursey]

On the Open MPI teleconf this morning Rich mentioned that he was  
noticing odd memory usage. It got me thinking, would it be useful for  
MTT to track important aspects of the process such as memory use?

Just a thought. I'm not exactly sure how we would report or record  
this, but if it is useful we can file a bug for it :)

Cheers,
Josh
