1) Ravenscar is purely about multi-tasking, and says nothing about the
sequential aspects of the language. Allocators (aka "new") are allowed
(but may be disallowed in safety critical contexts by other rules).
2) Did you look into Ada.Unchecked_Deallocation? It is a generic that
you instantiate to get the equivalent of "free".
