My understanding was this API is meant to be stable? That was one of the reasons I haven't touched its interface at all.

Sorry, I haven't updated its signature, will do. I've probably should also add the new function there, that would just raise a fatal error since it's meaningless to call it with multithreading disabled.
I mean the comment start. Documentation like this is the old LLVM style, and as we update code we also update the docs:
