Some users are sensitive to the short stalls that can be caused by oplog truncation, which can be a moderately heavy operation. This can be difficult to diagnose; we could make it easier to diagnose by logging each oplog truncation like we log normal operations. Since oplog truncations are infrequent events this could be logged without regard to the slowms threshold.
