Actually, let me rephrase also.

If this list were time-invariant, then there would be no issue here. 
We'd just have the first ever get create the list, cache it, then keep 
returning it.

But as I understand, the list is time-varying.  So we have two options:

1)  The first time the get is performed, create some object that stores 
the list, cache that object, always return that object in the future. 
When the list is supposed to change, update that object's state to 
reflect the new list.

2)  When the get is performed, if we have no cached object create a new 
object, populate it with the list and cache it.  Return the cached 
object (which we may have just created).  When the list is supposed to 
change, clear the cache.

Which of those two behaviors are we looking for here?
