* Fiber class

*
* This class implements fibers at a low level, thus allowing greater freedom
* to implement such patterns. This fiber class is 'threadsafe' only one fiber
* can be running at a time and threads will be locked while trying to yield to
* a running fiber until it yields. WARNING exchanging two running fibers between
* threads will cause a deadlock. In order to prevent a deadlock, each thread should
* have an intermediary fiber, you switch to the intermediary fiber of the current
* thread and then from it switch to the expected fiber. This way you can exchange
