Description Andrew Cagney 2006-11-22 17:27:08 UTC
This is easier than it looks, breakpoints do not need to be removed (but doing
so doesn't hurt) as the step will always go to the handler.

This is an interesting case. The TaskState mechanism is currently not setup to
preventively remove any breakpoints. Is there any mechanism to definitely know
that a Task has any pending signals? I assume that a signal could become pending
during the next ptrace-step and if so the step ends up in the signal frame.
