2001-11-13  JP Rosevear  <jpr@ximian.com>

 	* e-pilot-map.c (real_e_pilot_map_insert): only insert non-0 pids
 	into the pid map
 	(e_pilot_map_insert): remove and free old keys/values here -
 	including possibly orphaned keys
 	(e_pilot_map_remove_by_uid): only free things if they should have
 	been found
