This change moves the worker's *sharedMem into a buffered chan that acts as a mutex. The mutex can be locked by receiving from the chan; it can be unlocked by sending *sharedMem back to the chan. Multiple objects (like worker, workerClient, workerServer) may have references to the chan and may hold the lock across several operations. This is intended to fix a segfault that occurred when workerClient.fuzz accessed shared memory after it was already closed and unmapped by the worker's goroutine. workerClient.fuzz is executed in a separate goroutine so the worker can still receive messages from the coordinator (like being told to stop and clean up).
