I think I disagree : the current global initialisation is done by Init::Ini=
t.=20
We can, without breaking the ABI, change its behavior so it does nothing wh=
en=20
a particular environment variable is set.
We can add another class, let's say InitNG, which does what you suggested f=
or=20
Init.
This way people who want to do manual initialisation can do it by setting t=
his=20
variable.

Another way I just thought about is not to change Init::Init behavior, but=
=20
adding both another init class and a free function (probably a static=20
function of the new init class) which undo what Init have done and forces=20
it's destructor not to do anything.
The advantage is that the proper behavior of the program does not depend on=
 a=20
user intervention.
