Back-beta (and probably back-ldap) need to be able to recognize
intermediate response messages, as they are part of the protocol.
Probably, it would be a good idea to detect unrecognized response
messages and handle them nicely.

I'd notice that this type of operation might be less than ideal, since a
proxied refreshAndPersist operation will keep one thread of the proxy
busy all times waiting for further responses.

In that case you could use back-ldap with slapo-rwm.
