What is more efficient: Rec or Cont?
type Rec new Limited_Controlled with
record
Str: access String;
end record;
--
-- Code to automatically deallocate Str when Rec is finalized
--
or
type Cont is new (String);
(Note: in the real code it may be Interfaces.C.char_array instead of
String.)

Should be instead:
type Cont is new Containers.Indefinite_Holders(String);

Cont, because it makes more efficient use of the developer(s). Anything else is
only an issue if using Cont is preventing the system from meeting its timing
requirements.
