Something like that, yes... The easiest way I can imagine is to move *two*
windows over the image, say one 64k-sized window and a 1k-sized one. The
1k-sized one would only be used for input files which are smaller than 64k.
If the queue gets full, 1k-sized matches are dropped first.
In fact, jigdo-file did this for a while, but the code got too complex
IMHO, so I removed the feature...

You're right - it's just that the whole algorithm is already complicated
enough - <sigh>
