Re: storeGet() -> storeGetPublic() ?

On the flip side I am seriously considering making some time for a database base metadata index. Probably using the sleepycat engine
or something similar. I *am* interested in trading space for time. (Because O/S swapping is not terribly smart.) On the other hand I
may pick up Bugless's memory mapped index and bring it up to HEAD level.
