I just found the function encode-coding-region, I never knew it exists, thanks!
The log will eventually gets written out so this is good enough.

BTW, after second thought, I think this is probably a premature optimization.

What about not care about locking at all in the kv-store APIs and let
package author do it?

On the other hand, I’m currently implementing a high level persistent-variable
API that runs in idle timer. I can easily lock/unlock only once every idle timer
event (instead of before/after every kv-put) and now the cost should be
negligible.
