> The documentation states that
> {code}
> ZooKeeper logs transactions to a transaction
> log. After snapCount transactions are written to a log
> file a snapshot is started and a new transaction log
> file is created. The default snapCount is
> 100,000.
> {code}
> However, in implementation, snapshotting is done when logCount is somwhere in
> (snapCount/2, snapCount+1], based on the limit set at runtime:
> {code}
> if (logCount > (snapCount / 2 + randRoll)) {
> {code}
> as in
