 * Revision 1.4  1997/06/25  22:09:14  pvmsrc
 * Markus adds his frigging name to the author list of
 * 	every file he ever looked at...
 *
 * Revision 1.3  1997/04/10  17:53:55  pvmsrc
 * Externalized me_new()...
 * 	- for WT_RECVINFO usage...
 *
 * Revision 1.2  1997/04/08  19:41:12  pvmsrc
 * Added me_savetid to pvmmentry struct.
 * 	- for keeping track of original owner on persistent mboxes.
 * 	- allows more careful cleanup in a system reset, set me_tid to 0
 * 		but save original tid in me_savetid first...  :-)
