I'm not sure if you people are as amazed as me by this, so I'll just  
keep posting reports until someone tells me not to. :-)

After adding a couple of binary searches in well needed places (and a  
couple of new bugs that in a few cases affects the results) I'm now  
down at 1/8th of the time compared to RAMDirectory. That is really  
fast if you ask me.

The 5MB FSDirectory representation occupies about 70MB memory, but  
there are still a few things I can do about that.
