The test application lets run a thread at the highest priority that calls yield all the time - the system stays responsible when it runs, so it seems to work fine :) Changed the malloc implementation to use _kern_thread_yield() instead of snoozing. We should think about making this call public, too. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@16166 a95241bf-73f2-0310-859d-f6bbb57e9c96
