Thanks, I'm all poised to commit this.

But first, could you tell me why we would want an API function to
enable/disable temporal coherence on a per-object basis?  Under
what conditions is this useful and what are the appreciable benefits
in using this function wisely?  This'll both help me to understand
the justification for the patch and write a more-useful documentation
entry for the new API functions.

Thanks,
