- Put Simulation in stopped state before changing policy (doesn't 

prevent a sigsegv if you try to change it while the simulation
is running)
- Use a red color to indicate a blocked thread / unallocable request
in widgets
- TODO: try the deadlock test w/ the rr (NOT the rr_priority) cpu
policy. There's something wrong with the policy...
