HashTable::BucketSize();
I'm not a big fan of using the initial size here, since it means changes 
elsewhere to the sizing have to be reflected here. Can you just get 
HashTable::num_buckets() before trying to init the hash table?


Line 1251: UNLIKELY

Line 1252: status
Dead variable.

Line 636: UNLIKELY
Again, not sure this is hot enough to justify annotations.
