190Wait until the given lock is available and then acquires it and returns
191a Coro::guard object. If the guard object gets destroyed (goes out of scope,
192for example when the coroutine gets canceled), the lock is automatically
193returned.
194
195Lock names should begin with a unique identifier (for example, cf::map::find
196uses map_find and cf::map::load uses map_load).
