On a set too large for the quality guard's engine to sit beside the main one (8qaw: 123 M
observations; 8a1a), the main engine was ingested, found not to leave room, dropped and
ingested again after the guard - several seconds of ingest for nothing. The pre-pass's
engine merged the guard's very frames earlier in the run, so its card memory per reflection
is now kept (prepass_engine_bytes_ / prepass_engine_reflections_) and both engines are
reckoned from it before either ingests: the guard at its frames' reflections, the main
engine at all of them (observations add in proportion; rocking events and distinct hkl at
most in proportion). Beside where the two fit the card less the 3 GB reserve, otherwise
the guard first. The re-ingest path is gone.
7qij, 9v16, cytc: beside; 8qaw, 8a1a: guard first. Same merges, same numbers.
