The call to init should be idempotent

[layer8]

That can be difficult in a multi-threaded environment with dynamically loaded shared libraries. Or at least it isn’t something that’s generally expected to be guaranteed to work.

C++ "magic statics" handle that use case (but with hidden atomic flag load (& more) costs at each access)

[lokar]

Ideally they would do the explicit init at startup before starting threads
