  hm, last i checked counters were fully implemented as atomics, it seems now theres another internal bif for "write concurrency", is this new or was it always like this and did i just miss it?

    Already existed when it was first merged: https://github.com/erlang/otp/commit/fefb5d039e87ff7137e78b3...

    Atomics were introduced a while before `counters`, maybe you remember a custom implementation on top of that?

      nah, I probably didn't quite read the code correctly. Thanks for the link.

  What we really need is an atomic_term :)
