But is the startup time of apps that use a lot of stuff the most important thing? I'd say that the startup time of apps that *don't* use a lot of stuff is more important.

Yes, please. We switched to building almost all extensions as shared libs when we switched away from Modules/Setup to setup.py. --Guido van Rossum (home page: http://www.python.org/~guido/)
