> The failure is in TestReplication.queueFailover (fails due to unreplicated rows). I have
come across two problems:
> 1. The sleepMultiplier is not properly reset when the currentPath is changed (in ReplicationSource.java).
> 2. ReplicationExecutor sometime removes files to replicate from the queue too early,
resulting in corresponding edits missing. Here the problem is due to the fact the log-file
length that the replication executor finds is not the most updated one, and hence it doesn't
read anything from there, and ultimately, when there is a log roll, the replication-queue
gets a new entry, and the executor drops the old entry out of the queue.
