Combination of reference-counting as a first resort, with full garbage 
collection to deal with those less common cases where you have reference 
cycles. Trying to get the best of both worlds.

The trouble with reference-counting is it impacts multithreading 
performance. However, the CPython developers have a scheme to deal with 
this, by making the reference counts a little less deterministic (i.e. 
there may be a slight delay before they become fully correct). I think 
this is a complicated idea, and it may take them some time to get it fully 
implemented.
