Log Message:
Attempt to protect restartable atomic sequences of a traced process
being written to.  Breakpoints aren't good in a RAS.  This test isn't
infallible, since we can't protect memory which will be registered
as a RAS in the future.

Also, set the PC before attempting to single-step, so we can backout
from single-stepping.  Just in case we try to single-step into a RAS.
