The documentation simply states that if you set an identity, that is
used to associate resources with the socket. In practice, 0MQ holds
resources per binding socket, so that sets the limit for uniqueness.
In theory, this can change at any time, so the limit is application
wide. In further theory, the whole notion of durable sockets may be
dropped in future implementations since it's extraordinarily complex
in the code, and tends to create brittle architectures.

If you must use durable sockets, I'd advise using application-unique
identifiers or UUIDs.
