components - now, we divide the initialization of that service into two parts which allows this (before, most handlers were gone after boot). * Added debugger command that dumps the low memory handlers. * The slab allocator now registers its low memory handler with a higher priority, so that it'll run before the potentially heavier ones. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@22374 a95241bf-73f2-0310-859d-f6bbb57e9c96
