> There have been some occurrences of Oplog corruption during testing that have been traced
to failures in writing oplog entries to the .crf file. When it fails, Oplog.flush attempts
to write a ByteBuffer to the file channel. The call to channel.write(bb) method returns 0
bytes written, but the source ByteBuffer position is moved to the ByteBuffer limit.
