Ralph Castain b118779c08 It is okay for us to init the ORTE mca params multiple times. Indeed, it is absolutely required by orterun as the first time has to be done prior to parsing the command line, which means that the mca values haven't been parsed yet!
Add ability for sys admins to prohibit putting session directories under specified locations. Thus, they can now protect parallel file systems from foolish user mistakes.

This commit was SVN r18721.
