It's BDB with a very pessimal random write workload updating
transaction indexes with stuffed full of sync writes, interspersed
with an equal amount of random reads.
(The next version of the software will change the backend in several
ways, including replacing BDB with leveldb and its orders of magnitude
faster; but for now it's probably a fine FS abusive test case)
