Except that isn't true in Erlang (or other BEAM languages). Binaries larger than some threshold are managed on a shared-heap. I think a couple other things have been promoted to being managed that way too fairly recently.

That's not true in a number of cases, and thankfully what you said isn't right or the BEAM would truly be a disaster.
