<pre>Modern IDB: Ref cycle between IDBObjectStore and IDBTransaction
IDBTransaction has to retain a list of all object stores referenced during its lifetime, and object stores need a pointer to their transaction.
Fortunately it's easy to break this cycle: Once the transaction is aborting or committing, accessing its referenced object stores is no longer possible.
So at that time, the set of references object stores can be cleared, breaking the cycle.</pre>
