Follow-up simplifications after removing the zerocopy machinery, plus a real backpressure bug the cleanup surfaced: - SendImage(ZeroCopyReturnValue&) imposed a hard 2s deadline on enqueueing and then marked the connection broken. At high frame rate the 128-deep queue fills in tens of ms, so any filesystem stall longer than ~2s dropped the run even though the writer was alive and heartbeating -- defeating the whole BUSY-heartbeat backpressure design. Block instead while the peer is alive (!broken && active); the real liveness decision already lives in SendAll's peer-liveness timeout, which the writer's BUSY heartbeats keep fresh. This makes the queue path consistent with the send path: both wait out arbitrarily long stalls and only give up when the peer goes genuinely silent. - Drop the dead per-connection data_sent counter (written, never read) and the redundant ImagePusherQueueElement.image_data set on the TCP path (only the HDF5 pusher reads that field). - Add SetPeerLivenessTimeout() so the liveness window is tunable (and testable). Add TCPImageCommTest_StalledWriter_SurvivesViaHeartbeat: a controllable raw writer double connects, ACKs START, then stops draining for 4s while still sending BUSY heartbeats (peer-liveness window set to 2s). The run must ride out the stall on the zero-copy queue path and deliver all 1000 images. Verified to fail (115/1000 delivered, connection dropped) against the old 2s-deadline behavior.
