[development] The Drupal Diet - Making bootstrap faster

[David Metzler]

For some reason I was lying awake at night thinking about drupal boot  
strapping (dear lord help me).  And it occured to me that although  
the frequency of use is certainly the right measure to decide what to  
load, that it probably isn't by technology, so I came up with a  
couple of different ways to think about this.

BY MENU PATH
1) System stuff - api's etc that need loading all the time.
2) node viewing pages (node* paths/routes) (not so sure this would work)
3) User settings (not sure about this one, but maybe anything with a  
user* menu path
4) admin pages (basically everything with an admin/blah route path

You could even consider doing the admin pages based on a permisssions  
test (access admin pages).   The module_name.module files would  
always load, but maybe there would be room for a  
modulename.admin.module or a modulename.user.module  file that would  
be conditionally loaded based on either path or user permissions or  
some other criteria.

BY NAMESPACE
Or alternatively a namespace based approach where when a module is  
going to make a call that relies on another module it basically does  
an "import" of  namespace (the way its done in java)  This would make  
a bootstrap call that would load the modules that claim that  
namespace. (etiher in .info files or in a hook).
