The only thing we could do with the reset after this point in the schedule() method, if the reset had not yet been inserted into the inputQueue, is to complete the `requestBodyCF` and this would have already been taken care of at line 595 in incoming_reset. So I don't believe the scheduler would need to run again after this line (or the other like it)
