I'm looking at implementing restartable atomic sequences for
PowerPC but I ran into a few issues that need clarification.

The first is what happends if a trap happens withing a RAS
that's supposed to invoke the debugger?  Do I dismiss the
trap?  Ignore the breakpoint?  kill the process?  What if
someone issue a trap instruction (breakpoint) while inside
a RAS?  ignore the breakpoint?
