Galen Shipman 6ed255f114 Substantial changes to the CM PML, allows us to have a very thin request for
all but buffered and persistent requests. Unfortunately we were note able to
reuse the pml_base_request_t as it was just too heavy for our needs. Lots of
code for 2/10 usec ;-) 

This commit was SVN r10810.
