* Improved timing in SnapC Full Global Coordinator
* Improved scalability of the SnapC Full protocol
* Minor improvements to the error reporting mechanisms in SnapC and FileM
* Improved the memory usage of the metadata routines - now the owner of the data is more explicit.
* Added a FileM hint to indicate when files stored locally can be moved to/from a globally mounted file system using just the 'cp' command instead of the 'rcp/scp' command. Slightly improves performance, but not too drastically. Can be set using the following SnapC MCA parameter: {{{snapc_base_global_shared=1}}}
* Implement the ability to throttle the number of outgoing connections in FileM. At larger scales this type of explicit throttling helps prevent overwhelming the HNP machine. Default: 10, set via MCA parameter: {{{filem_rsh_max_outgoing}}}
* Add a few diagnostic/debugging features to SnapC and FileM.
