5db908b1c5 Separate ProcessManager to a mod. 2018-10-24 00:38:22 +08:00
WangRunji
f7eb09e856 Multicore processing WORKS! Basically ... 
- Rewrite processor.rs
  Refactor to `Processor` & `ProcessManager`
- Use Box<dyn> instead of generic.
- Wait/sleep/wakeup is not supported yet.
  I'm considering to implement them with WaitQueue.
