      New implementation of BLACKHOLEs · 5d52d9b6
      Simon Marlow authored
      This replaces the global blackhole_queue with a clever scheme that
      enables us to queue up blocked threads on the closure that they are
      blocked on, while still avoiding atomic instructions in the common
      case.
      
      Advantages:
      
       - gets rid of a locked global data structure and some tricky GC code
         (replacing it with some per-thread data structures and different
         tricky GC code :)
      
       - wakeups are more prompt: parallel/concurrent performance should
         benefit.  I haven't seen anything dramatic in the parallel
         benchmarks so far, but a couple of threading benchmarks do improve
         a bit.
      
       - waking up a thread blocked on a blackhole is now O(1) (e.g. if
         it is the target of throwTo).
      
       - less sharing and better separation of Capabilities: communication
         is done with messages, the data structures are strictly owned by a
         Capability and cannot be modified except by sending messages.
      
       - this change will utlimately enable us to do more intelligent
         scheduling when threads block on each other.  This is what started
         off the whole thing, but it isn't done yet (#3838).
      
      I'll be documenting all this on the wiki in due course.
