> We currently use a WeakReference to hold elements in memory. This is convenient, but
when we have exhausted the memory, the GC takes forever to reclaim the weakReferences, slowing
down the code up to a point it's unusable.
> We should rather use a LRU Cache to store a limited amount of elements, and make it configurable.
> We should keep the WeakReferences for those having enough memory. (to be discussed)
