> Before reseting the engine, we suspend the execution of the guilty
> request, so that we can continue execution with a new context while we
> slowly compress the captured error state for the guilty context. However,
> if the reset fails, we will promptly attempt to reset the same request
> again, and discover the ongoing capture. Ignore the second attempt to
> suspend and capture the same request.
