~~SERVER-47602~~ reported an issue with out-of-order processing of _killOperations for hedged reads. This could cause leaking of cursors created on mongod servers to serve hedged reads. This ticket should write a repro and fix the issue to avoid leaking cursors while hedging reads.

Edit: cancellation of any in-progress request is susceptible to this issue, even when not hedging.
