Maybe you could consider doing less during construction at loadtime.
I usually define all static objects, during construction they only register
themselves (or some initialisation functions) to some static repository.
Then at runtime, before making use of those objects, everything gets
initialised by calling some static function "InitializeAllTheStuff();" which
inspects the repository and does what has to be done. So all objects are for
sure created before you initialise.
De repository is about the only object that needs to be wrapped inside a
function, and it doesn't show up in the interfaces.
Instead however, the initialisation function pops up in you interface and it
has to be called once. IMO that's not too bad.
