Subject: - Patch #221964 by chx, dopry, webernet, moshe, webchick,
 justinrandall, flobruit   et al.  Can you say 'registry'?  Drupal now
 maintains an internal registry of   all functions or classes in the system,
 allowing it to lazy-load code files as   needed (reducing the amount of code
 that must be parsed on each request). The   list of included files is cached
 per menu callback for subsequent loading by   the menu router. This way, a
 given page request will have all the code it needs   but little else,
 minimizing time spent parsing unneeded code.
