There seems to be a minor problem releasing memory grabbed during the
initial scan; All three times I've used a 6.0 beta to scan my library,
it's gone to a steady state usage of 60MB and then dropped by about 10
MB after restart. Here's a picture of memory consumption and processor
activity during startup -- it was rechecking the files during this
timeframe, then finished up neatly before the data scrolled off

So, don't assume that initially poor memory usage is the final story
until you've restarted.
