lock -- therefore move the OPAL_THREAD_UNLOCK after the if-OMPI_ERR_TEMP_OUT_OF_RESOURCE block. - As mca_rcache_rb_mru_delete is the only setter of rc, move the error-check right after mca_rcache_rb_mru_delete. - Removed a few nitty ompi/info/info.h and orte/util/show_help.h This commit was SVN r20355.
