A drawback is that careful management of these ressources is no more
possible. If the choices made by module designer to ensure security do
not fit well your problem, you are left with no option other than
writing poorly behaving applications.

In contrast, given a module that delegates ressource management to its
users, it is fairly trivial to wrap modules's functionnalitites into a
module that automatizes ressource management in a way that will fit
many uses.

One would write an `EasyLazyUnix', `CookedUnix' or `UnixChest' module
with automatic deallocation of ressources.
