Seems reasonable.

My implementation maintains using the linear list for sequences up to a
defined threshold (currently 32) then it moves everything over to a
hashtable and free's off the list.

Did you check how it would perform if you just always used the hash table? Or if you just have a single entry before you move to hash table, ie. set the threshold to 2? That would be slightly simpler.
