You may explain the purpose of the function here, like mention Cinder JIT and Pyjion.

I'd rather not have a "purpose". We should state clearly what the function does, not bless some particular use case.

Could you add a warning that the new function pointer must have exactly the same behavior as the unaltered function.
I am a little concerned that C extensions will abuse this, and we will have deal with the bug reports.
