Erlang doesn't share data between VM processes (green threads) and each process has its own heap, so you don't need to stop-the-world. Your GC can run concurrently with other live processes while still serving clients. Erlang also gives you the ability to manually invoke the garbage collector per-process so you can run it at more optimal times of your own choosing.
