I think it is not a good idea to have collections of Directory_Entry_Type.
Depending on the implementation, Directory_Entry_Type might use some system
resources, locked until Directory_Entry_Type finalization.

Yes, storage pools is an excellent tool to construct containers of limited
objects. It is a pity that Ada.Containers does not use this opportunity.

Another solution, used in the Simple components, is to have specialized
containers of  pointers. The container becomes responsible to free pointed
elements upon removal or replacing.
