Could we have a performance test (in t/perf) demonstrating this?

Document what this function does? Also, this function probably needs a
better name.

The documentation above duplicates what's in the header file, so we can
probably omit it.

This doesn't seem to be used elsewhere - do you plan for a future patch
to use it?
