Actually, I should have said recursive, not reentrant.

While I agree on removing the unused and potentially problematic
debugging machinery, I'm not convinced of the benefits of removing the
pure Python RLock implementation. To quote Charles-François from the
tracker issue: "Now, the fun part: this affects not only RLock, but
every Python code performing "atomic" actions: condition variables,
barriers, etc. There are some constraints on what can be done from a
signal handler, and it should probably be documented."

Remove the pure Python RLock doesn't seem to actually solve anything -
it just pushes the problem of fixing the signal interaction back onto
third party users that are even more ill-equipped to resolve it than
we are.

Regards,
Nick.
