Most of the comments are available on the Task structure itself, but this commit is aimed at making FFI-style usage of Rust tasks a little nicer. Primarily, this commit enables re-use of tasks across multiple invocations. The method `run` will no longer unconditionally destroy the task itself. Rather, the task will be internally re-usable if the closure specified did not fail. Once a task has failed once it is considered poisoned and it can never be used again. Along the way I tried to document shortcomings of the current method of tearing down a task, opening a few issues as well. For now none of the behavior is a showstopper, but it's useful to acknowledge it. Also along the way I attempted to remove as much `unsafe` code as possible, opting for safer abstractions.
