> UUID.randomUUID() is really slow, it's much faster to generate a single namespace UUID
with randomUUID() and use that + a counter with UUID.nameUUIDFromBytes(byte[] name).
> Because the uniqueness properties of this other scheme might be different, we should
have the uuid generation strategy be configurable.
