But the new code doesn't make anything worse, it only makes things better.

If you're only using TT via a Registry program then you'll get the same
set of modules loaded when the code does "use Template" instead of 
being trickle loaded as the various different parts are required.

If you're using TT via a non-registry program then you'll get all the 
core modules loaded at startup time in the parent process instead of 
waiting around and loading in the child processes.

So now it'll do the right thing most of the time, and the rest of the 
time, it'll do the no-worse-than-before thing.
