Well, it takes me days to understand and fix these issues myself
too.  ;-)  It's just the nature of the beast...

I see this in sync vs async:

 PASS: gdb.python/py-finish-breakpoint.exp: set FinishBreakpoint with default frame value

Do you see it too?

I looked at this a couple months ago, but didn't make much progress.  I'll try to
figure it out next.
