> A Prevayler-based in-memory backend will save major disk IO down the line when used to replace the system backend partition.  All major subsystems that will be made more robust after subentries are implemented will most likely use the system partition to store persistent information.  Prevayler puts an entire db into memory, loading it on startup.  Right now the system partition parameters for JDBM are set to use as much cache as needed, which should result in similar behavior but in practice this has not proven to be the case.
