Comment (by sebastian.huber):

 [[Image(resource.png, center, 60%)]]
 This is an example resource dependency tree with sixteen threads t0 up to
 t15 and sixteen resources r0 up to r15.  The root of this tree is t0.  The
 thread t0 owns the resources r0, r1, r2, r3, r6, r11 and r12 and is in the
 ready state.  The threads t1 up to t15 wait directly or indirectly via
 resources owned by t0 and are in a blocked state.  The colour of the
 thread nodes indicate the scheduler instance.
