That doesn't really work. It may not be possible in all cases.

That's the point of the One Definition Rule: ::operator new() should be the 
same for everyone.

Note that some _platforms_ break the ODR, notably Windows, but also to some 
extent Mac. On Linux and other ELF platforms it's very easy to add ::operator 
new() to your application code and then all libraries will be using it.
