A simple brain dump about lazy module resolution -- as I'm yet to fully understand the code.

Lets say you could immediately map resource to owning module.
e.g. based on the package ->  *org.jboss.foo* is the module name, my class is *org.jboss.foo*.bar.Baz
Or any similar mechanism would do.

We could then lazy load the first level / near module dependencies,
only fully initialize it on demand -- when first resource lookup is hit,
and again have its first level / near dependencies lazy.

This could be done optional, by default, as we currently do, resolve the whole graph at start.
Perhaps pushing it a bit :-), we could even specify the depth / level of resolving.

A few observations:
* OSGi has this similar notion of lazy resolve - how do we do it now?
* if I'm not mistaken, and I think Flavia was thinking about the same issue, we can reduce visiting
  --> simply (recursively) reuse paths from own children, no need to visit them

Wdyt? Or, how much work this would be?
I can try to hack something, but any input is appreciated.
