[development] Patch review

[Dries Buytaert]

Hello world,

I'd like to see _rigorous_ reviews of the following patches:

   1. Pave the path for CCK (http://drupal.org/node/62340)
   2. Install system (http://drupal.org/node/48732)
   3. File based caching (http://drupal.org/node/45414)
   4. Separate mail backend (http://drupal.org/node/28604)

NO dump +1's please, but careful reviews with eye for detail,  
usability and performance.  Yes, this takes more than 5 minutes of  
your time! :-)  A while ago it was suggested that we do a better job  
defining APIs so we don't have to break them that often; this would  
be a great time to review the APIs of above patches.

Thanks for your help!
