I'd say that the essential feature of JACK is not that it is a
callback based system, but that it presents and expects audio
data in fixed size blocks and enforces the rule that all clients
must have processed a block before the next arrives.

This could be done with blocking as well as with a callback,
and indeed it would be useful if JACK offered that option.
