Start a lot of copies of the above script going in separate windows of
a sparc workstation (say 7). Then wait. Eventually:

STATUS:Passed.
STATUS:Passed.
STATUS:Passed.
STATUS:Passed.
STATUS:Passed.
STATUS:Passed.
STATUS:Passed.
STATUS:Passed.
STATUS:Passed.
STATUS:Passed.
STATUS:Failed. daemon group not destroyed
algol%

The reason that multiple copies are required is that paging is being used to
disrupt the timing of ThreadGroup destruction.

For more information see the bug filed against this (in my opinion bogus) test:
Bug ID 4188006.

I'll try to get around to filing an RFE against the specification asking for
more precision about questions of Thread and ThreadGroup destruction. There are
multiple method calls with indeterminate results.
