This worries me a little bit. MemoryCollection obviously uses a lot of
memory. Where possible we should avoid having to place the complete
set of tracks in memory and rather rely on the design goals of
QueryMaker to create them on demand. I would think Nepomuk is the
perfectly suited for that. Can you explain what blocked you and
decided to switch to MemoryCollection?
