New Revision: 21623

Modified:
   branches/db4o/freenet/src/freenet/node/Node.java
Log:
Use BTree-based freespace tracking.
This will be slightly slower than the default (RAM-based freespace tracking), 
but the default uses very large amounts of non-collectible memory (73MB out of 
128MB on my long-lived db4o node!).
