orte_system_info.nodename so that cleanup and the like occur correctly. Otherwise, the daemon on localhost and an MPI process can have different ideas on what the local nodename is, and that lead to all kinds of badness with both process killing and cleanup. Also fixes the annoying ssh keys problem when sshing to localhost. - modify the rsh pls to ssh to localhost if the target nodename is the same as orte_system_info.nodename AND is not resolvable (ie, ssh to would fail). Otherwise, ssh to nodename. This should work around the issues Ralph was seeing with ssh failing on his laptop (since the above change undid the previous fix to this problem). - Small change to ompi_ifislocal() to squelch a warning message about unresolvable hostnames when checking to see if a name is, in fact, resolvable. - Force ORTE process to have same nodename field as it's starting daemon (assuming it was started using the fork pls), so that the fork pls can properly kill the process, and cleanup its session directory on abnormal exit.
