Well the problem is essentially the same whether you interpret dependency ranges eagerly during installation of a root "application" module, or lazily the first time the 
application is run and caching thereafter, or simply every time it is run. Obviously a user might accept a twenty-second pause installing a module while rejecting a 
one-second pause when launching it, but resolution as per Jigsaw's current specification can take time exponential in the number of modules - thus (potentially) 
intractable even for installation.
