Small problem: in VMS version 5, G^EXE$ALONONPAGED must use a spinlock. So, the
proper IPL is now IPL$_POOL. This is one of the things that must be changed  in
existing drivers and that have NOT been reported in DEC manuals (together  with
some other details that I will not discuss here).

Good upgrade !
