+Create a new pool instance. In most cases you just need one pool.
+Note that the returned object "owns" the pool, i.e. if the object is

+break this ownership relation.
=== ATTRIBUTES ===
pool.free()
pool.free()
-Free a pool. This is currently done with a method instead of relying on
-reference counting or garbage collection because it's hard to track every
-reference to a pool.
+Force a free of the pool. After this call, you must not access any object

+Break the ownership relation betwen the binding object and the pool. After
+this call, the pool will not get freed even if the object goes out of
+scope. This also means that you must manually call the free method to free
+the pool data.
