Fix race condition between insert_new and lookup in ETS hit/5#175
Conversation
Handle the case where an ETS entry is deleted between insert_new and lookup calls in TokenBucket.hit/5 and LeakyBucket.hit/5. This could occur during cleanup races or ETS owner process restarts, causing a MatchError on the empty list. Now gracefully re-inserts a fresh entry when lookup returns []. Closes #173
