In article <293@berlin.acss.umn.edu>, grg@berlin.acss.umn.edu (George Gonzalez)
suggests a way to do non-interfering tail patches by setting the trace trap
bit in the PSW on the stack.

This won't work because the trap dispatcher discards the old PSW and returns
with an RTS -- it does not return with an RTE.
