//            -> chanEditMapLock -> osdLock

//            -> timerIdLock
//            -> mainLoopCondLock
//            -> channelGroupLock
//
// When holding one of these locks, you may lock any lock of  the locks to
// the right of the current lock, but may not lock any lock to the left of
// this lock (which will cause a deadlock). Nor should you lock any other
// lock in the TV class without first adding it to the locking order list
// above.
//
// Note: Taking a middle lock such as askAllowLock, without taking a
// playerLock first does not violate these rules, but once you are
// holding it, you cannot later lock playerLock.
//
// It goes without saying that any locks outside of this class should only
// be taken one at a time, and should be taken last and released first of
// all the locks required for any algorithm. (Unless you use tryLock and
// release all locks if it can't gather them all at once, see the
// "multi_lock()" function as an example; but this is not efficient nor
// desirable and should be avoided when possible.)
