  2. Per-thread scheduling. Closes rust-lang#682. 

    Tasks are spawned on a random thread. Currently they stay there, but
we should add task migration and load balancing in the future. This
should drammatically improve our task performance benchmarks.

  3. Re-removing a test case that was moved during the big test suite over…

  4. Adding a function to stdlib to set the min stack size, for programs 

    that absolutely will not succeed with a large default stack. This
should be removed once we have stack grown working.

Also updated word-count to succeed under the new test framework.

  5. Made task threads wait instead of sleep, so they can be woken up. Thi… 

    …s appears to give us much better parallel performance.

Also, commented out one more unsafe log and updated rust_kernel.cpp to compile under g++

  6. Adding upcalls to to ref() and deref() tasks. This is the first step … 

    …towards atomic reference counting of tasks.
