What if an object you created, "A" has a dependence on another object "B"
that isn't reflected in the properties of A (i.e. no property of A is a
reference to B)?

Is the best way to inform the GC of this to use JS_AddRoot(B) in A's
constructor
(and a corresponding JS_RemoveRoot(B) in A's destructor)?
