I've played around with it a little more, and even the memory during the same
session seems faulty. It works very well for some narrow purposes during the
same session. For example if you analyze 3 lines then reduce to 1 line, it
proceeds almost immediately without significant loss of memory. But if you play
around very much, go backward or forward through the analysis manually, it loses
prior knowledge. So it just doesn't seem to be working right memorywise,
presumably a problem with the .pl2 file or the operational system that uses it
(shredder.exe?).
