Description

As a result of the new cleanup approach introduced with OAK-3348 (brutal) a compaction cycle that is not successful (either because of cancellation of because of giving up waiting for the lock) leaves garbage behind, which is only cleaned up 2 generations later.

We should look into ways to remove such garbage more pro-actively.
