Our largest application here is installed with SYSPRV and we will never
have the problem because the main routine drops it priviledge as part
of initialization.  Then the application takes priviledge only when
it needs it and gives it back right away.  Priviledge is generally required
in our application for opening the shared data files.  We have a routine
that opens data files and the priviledge code is in there.  This really
is a restatement of the maxim "Take priviledge only when you need it".
