More work on word-count.
...
Updated the MapReduce protocol so that it's correct more often. It's
still not perfect, but the bugs repro less often now.
Also found a race condition in channel sending. The problem is that
send and receive both need to refer to the _unread field in
circular_buffer. For now I just grabbed the port lock to send. We can
probably get around this by using atomics instead.

Add an unsupervise builtin and function to std::task
...
Calling task::unsupervise de-parents the current task, with the result
that failures do not propogate up the task tree.

This is the mega-ucontext commit. It replaces the task switching mechanism with a new one inspired by ucontext. It works under Linux, OS X and Windows, and is Valgrind clean on Linux and OS X (provided the runtime is built with gcc).
...
This commit also moves yield and join to the standard library, as requested in #42 . Join is currently a no-op though.
