Tests reproduce the MemoryError: Buffer overflowed crash by verifying that event_iterator drains pending position updates at timepoint boundaries. Without backpressure, a slow updater causes z-stack frame data to accumulate in the ThreadPoolExecutor queue faster than it drains.
Prevents unbounded executor queue growth that caused MemoryError: Buffer overflowed during long DynaTrack acquisitions. When the updater is slower than the acquisition rate, z-stack frame data accumulated in the ThreadPoolExecutor queue without bound. Now event_iterator detects timepoint transitions and blocks until the pending update completes.
