Didn't I read in the ILE manual that it has something to do
with protecting the default action group and OPM from some
of the performance enhancements that come from using the
action groups?

If I remember correctly, procedures used in a named (or
*NEW) action group are kept more "at the ready" for another
call, for faster execution of subprocedures, but that at the
last exit of the last program call to that action group, it
all goes away. Yes? Or?
