 Wait until the given lock is available and then acquires it and returns
 a Coro::guard object. If the guard object gets destroyed (goes out of scope,
 for example when the coroutine gets canceled), the lock is automatically
 returned.
+Locks are *not* recursive, locking from the same coro twice results in a
+deadlocked coro.
 Lock names should begin with a unique identifier (for example, cf::map::find
 uses map_find and cf::map::load uses map_load).
