222Wait until the given lock is available and then acquires it and returns
223a Coro::guard object. If the guard object gets destroyed (goes out of scope,
224for example when the coroutine gets canceled), the lock is automatically
225returned.
226
227Lock names should begin with a unique identifier (for example, cf::map::find
228uses map_find and cf::map::load uses map_load).
