+          constraints are not (yet) implemented in the kernel, a job must
+          tell Litmus when it is waiting for tokens. Litmus boost's the
+          priority of waiting jobs (which are expected to be well-behaved
+          and sleep while waiting for tokens) to ensure bounded priority
+          inversions. Litmus may also change a jobs release/deadline depending
+          upon when the jobs input tokens are generated.
