TODO

Test in real life applications

Yac is lockless, that means, there could be a chance you will get a wrong data(depends on how many key slots are allocated and how many keys are stored), so you'd better make sure that your product is not very sensitive to that.

if you use that, please provide it via extension

Core not interested in Yac at the current stage. Can be supplied through an extension if somebody really needs/wants it.
