Absolutely! I added a short example implementation of a mutex to the RFC under https://wiki.php.net/rfc/fibers#how_do_various_fibers_access_the_same_memory. The code uses a simple queue of fibers waiting to access the mutex to acquire and release the lock. A channel might be implemented with a queue of messages where the receiving fiber suspends if the queue is empty. Sending a message on the channel would resume a suspended fiber that was waiting to receive a message. Hopefully that helps. If something is still unclear or an additional example would help, don't hesitate to ask. Cheers!
