223Wait until the given lock is available and then acquires it and returns
224a Coro::guard object. If the guard object gets destroyed (goes out of scope,
225for example when the coroutine gets canceled), the lock is automatically
226returned.
227
228Lock names should begin with a unique identifier (for example, cf::map::find
229uses map_find and cf::map::load uses map_load).
