library

I stumbled across the WB on-disk B-tree library:

http://people.csail.mit.edu/jaffer/WB

It seems like it could be useful for my purposes (swapping data to disk during very large statistical calculations that do not fit in memory), but I was wondering how stable it is. Reading the manual, it seems worringly 'researchy' - there are sections labelled [NOT IMPLEMENTED] etc. But maybe the manual is just out-of-date.

So, is this library useable? Am I better off looking at Tokyo Cabinet, MemcacheDB, etc.?

By the way I am working in Java.
