> To determine package space consistency, the resolver algorithm must calculate
> the package space of each module involved in the resolve operation. Since the
> resolver algorithm is stateless, it ends up re-calculating package spaces of
> resolved modules again and again. One of the more time consuming aspects of
> package space calculation is determining "uses" constraints, since they are
> transitive. The current algorithm re-calculates "uses" constraints for both
> resolved and resolving bundles. However, the "uses" constraints are only
> necessary for determining if a resolving bundle's package space is
> consistent; a resolved bundle's package space is consistent by definition
> (unless it is performing a dynamic import). Therefore, the resolver could be
> optimized by only calculating the "uses" constraints of resolving (and
> dynamically importing) bundles and not doing so for resolved bundles.
