Description

When we have a base with, say, 10000 entries, deleting one of them takes forever. A short analysis conducted by Stefan Seelmann shown that the problem lies in the way we handle indexes (log for one entry) :

JdbmStore: lookup in 0ms
JdbmStore: drop alias indices in 0ms
JdbmStore: drop ndn index in 78ms
JdbmStore: drop updn index in 34ms
JdbmStore: drop onelevel indices in 426ms
JdbmStore: drop sublevel index in 525ms
JdbmStore: drop parent onelevel index in 0ms
JdbmStore: drop existence index in 3ms
JdbmStore: master delete in 0ms
JdbmStore: sync in 7ms
