models: Memoize identical instances automatically
...
This combined with the previous changes has brought the memory use for a 14k
track test-set down from about 75MB to 17MB or so. Note that this does however,

avoid it.

models: Shortcut case where copy didn't change anything
...
We no longer copy in this case and will just give you the same instance back.
