Measured on rc.169 over rotation sweeps from 2.5 to 18 megapixels: both peaks
fall in scaling and merging, and both track the number of integrated
observations rather than the detector size - two sweeps on the same detector
differ five-fold. Device memory is linear in -N at about 8 bytes per detector
pixel per worker over a fixed floor, so the 16 GB card that fits four light
runs fits one heavy one. --no-merge and -N lower the peak; --no-export-unmerged
was measured and does not - it saves disk, not RAM.
Also records what happens when the card is too small: device decode, the
beam-stop projection and an indexer thread degrade to the host, everything else
fails the run with a non-zero exit rather than returning a short dataset.
