Description

SegmentBufferWriter#checkGCGen is an after the fact check for back references (see OAK-3348), logging a warning if detects any. As this check loads the segment it checks the reference for, it is somewhat expensive. We should either come up with a cheaper way for this check or remove it (at least disable it by default).
