they were never freed unless the cache was destroyed (I just wondered why my system would bury >1G in the magazines). * Made the magazine capacity variable per cache, ie. for larger objects, it's not a good idea to have 64*CPU buffers lying around in the worst case. * Furthermore, the create_object_cache_etc()/object_depot_init() now have arguments for the magazine capacity as well as the maximum number of full unused magazines. * By default, you might want to initialize both to zero, as then some hopefully usable defaults are computed. Otherwise (the only current example is the vm_page_mapping cache) you can just put in the values you'd want there. The page mapping cache uses larger values, as its objects are usually allocated and deleted in larger chunks. * Beware, though, I couldn't test these changes yet as Qemu didn't like to run today. I'll test these changes on another machine now. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@35601 a95241bf-73f2-0310-859d-f6bbb57e9c96
