I want the protected type to be a type so that users of the package
can make instances of it. In other words, it is not a singleton (this
would justify moving the state to the package body).

The "real" solution is synchronized interface + derived hidden
implementation + factory function, but this solution happens to be
also very heavy-handed and... fragile with regard to the ability of
today compilers to properly digest it. Sigh.
