Erlang processes are not pure, but they do have their own
memory heap, making it possible to do stop-and-copy GC per
process. I think the share-nothing model is more important
than purity.
There are some functions that allow Erlang processes to update
"global state" (e.g. the ETS hash and ordered_set tables), but
they are ensured to be atomic by the runtime system. You could
model each of these functions using normal erlang processes.
