We try to cleanup after ourselves if possible so future mallocs
can find memory more easily.  We do not need to nil the object
slot, just String#clear since we're exiting the function soon,

Followup to commit bb774680aae0a827f887761b18da304aa94111cc
("use String#clear for short-lived buffers we create")
