I have in a couple cases created a _MODULE_init() function that will
load libraries (and perhaps check for their existence and
configuration, etc) on an "as needed" basis. This does have the
benefit of not necessarily including things on the pages when they're
not needed. The one caveat sometimes can be scoping for class
definitions. However, particularly with larger libraries, *not*
having them in RAM for each request is usually a pretty big benefit.
