jsteemann 0b8b17a9d1 avoid find() -> insert() sequence (#11743) 
Summary:
when a key is recorded for locking in a pessimistic transaction, the key is first looked up in a map, and then inserted into the map if it was not already contained.
this can be simplified to an unconditional insert. in the ideal case that all keys are unique, this saves all the find() operations.
