  42  * The test creates an rmid with a special security manager.  After
  43  * rmid makes two registrations (which is greater than rmid's
  44  * snapshotInterval) the security manager stops allowing rmid to write
  45  * to update and snapshot log files in rmid's log directory.  The Test
  46  * registers an Activatable object twice with different group ids.
  47  * The second registration will cause rmid to have to write to a
  48  * LogFile (it causes a snapshot) and the security manager will not
  49  * allow the file write to happen.  The test makes sure that rmid
  50  * shuts down in a graceful manner without any explicit request to do
  51  * so.  The test will not exit for 400 seconds if rmid does not exit
  52  * (after that time, the test will fail).
