      Description

      I was running aggregations and writing output to a file, but my database I was analyzing was "local" DB. Apparently if _aCommitIsNeeded detects that we have a write lock on "local" DB it fasserts() but since I'm running a regular build, it just continues fasserting till I kill -9 it.
