Chuck,

I could be mistaken, but IIRC there were some problems with some of
the larger shops using up permanent addresses with lots of create /
deletes; which required a reload of the LIC/OS(?) to recover from.

That of course didn't go over well, and IBM ended up making some
changes in a v5 release somewhere that as I understand it allow for
permanent addresses to be cleaned up for reuse at IPL.

Again, I could very well be mistaken...

  A permanent address for an object which has since been deleted is
not reused.  All future reference to the pointer will effect MCH3402
to denote the condition of "object destroyed".  Note that the object
to which it points no longer exists, so the message can not be so
kind as to inform what the last-known object name was... since the
name is not part of the pointer, but instead part of the object
addressed by the pointer.

  I am not sure to what "'not reused' is not completely true
anymore" alludes.?
