Well no one is going to step up and document a current hole that they
may know about. Two holes I happen to know of that were fixed so long
ago that it can't possibly matter now, are the whole GAM implementation,
which happily accepted a user-supplied address and branched to it in
supervisor state, and the ability of any user to run a line trace on a
37x5 without the possibility of control by the installation. These were
fixed in the 1970s and 1980s respectively.

I those, since we didn't use any of that type of equipment.
OS/360 had a FREEDBUF macro that could SYNCH to a user-supplied exit in
Supv. state Key-0. IIRC, it was part of BDAM.
