> In POCombinerPackage, we create bunch of InternalCachedBag, the number of which is the
number of algebraic UDFs we use. However, when we create InternalCachedBag, we use the default
construct which assume we only create 1 InternalCachedBag in the system. It turns out we reserve
way to much memory to InternalCachedBag.
