Not only that, but an article in Electronics World (London) says that
a fast charge is better than a slow charge because it forms smaller (and
more mixed-up) crystals. They advocate charging very fast (even 1-hour
charge) if the temperature of the cell is monitored.

Hmmm, anyone for a fast charger that you put into the refrigerator?
Or one with a thermoelectric cooler?
