Ok, to start with, I deleted all the files in .limeware except createtimes.cache and
fileurns.cache (it takes ages to regenerate these). This cleared up the above-mentioned startup problems (<strike>except for some reason that LW is reconnecting as leaf rather than UP, even though the latter is enabled</strike>it is now running as UP). Now, I startup, and within 60 secs, LW starts grabbing >99% CPU.

I have a 2048/1024 ASDL connection and am sharing ~4,5k files
