> Currently, all Spillable DataBags get registered by the BagFactory at the moment of creation.
In practice, a lot of these bags will not get large enough to be worth spilling; we can avoid
a lot of memory overhead and cheapen the process of finding a bag to spill when we do need
it, by allowing Bags themselves to register when they grow to some respectable threshold.
