But this isn't happening in my scenario. If necessary, I can add an event
timeout or maximum size event value to prevent this infinite memory
requirement.

Block D just needs 10 more samples from block C for fully see the event,
which cause the enable signal to be produced. But block C has consumed all
it's inputs to produced as many outputs as possible. So block C just needs
block A to output samples.

The question is, why does block A not produce samples (we have not reached
EOF)?
The input buffer to block B & C are both empty, so shouldn't block A be able
to produce outputs?
Block B still has 10 samples left in it's output buffer. Is that preventing
block B from receiving inputs?
