Sorry for the delay in reviewing this. I don't know much about ptrace
except as a user, but this seems to make sense. The only request I have
is for you to write a small comment describing each new function you
introduce. The patch is OK with those changes.

PS: I assume you tested the change on 2 systems, one with the
functionality, and one without?

Thanks,
