Using picam2.capture_request(flush=?)

[juanmf]

I need to ignore stalled shots in buffer, I plan to use the newly added flush parameter #851
I noticed I can set a time in the future as well. Can I use it to "delay" between snapshots as follows?

        start = time.monotonic_ns()
        for count in range(1, 1000):
            # Simulate time.sleep(0.02) between shots
            request = self.picam2.capture_request(flush=start + count * 20_000_000)
            request.release()
        

Instead of a more conventional time.sleep(0.02)? (sleep is horrible with accuracy for small delays).

Thanks!
