limit, but this is not yet enforced. Added getter functions. team_init() now returns a status_t. System info stuff is now globally initialized in main(). get_system_info() now also reports the number of used pages, and calls the architecture dependent function. git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10315 a95241bf-73f2-0310-859d-f6bbb57e9c96
