Update the rsh tree spawn capability so we spawn the next wave of daemons before launching our own local procs. Add an ability to encode nodenames for large clusters with contiguous node name numbering schemes - this allows communication of all node names in a few bytes instead of tens-of-bytes/node. This commit was SVN r18338.
