I want to add some more questions:

5) How well is GnuRadio suited for real-time operation?

5.1) Specifically - is memory allocated from heap with malloc() or it
supports non-blocking memory pools?

5.2) Can the whole flowgraph be executed from a single thread to
minimize cross-thread communication overhead (and jitter)?
