Apparently you can set the ID of a stack to a higher number than it
currently is, but attempting to set it to a lower number will generate
an error stating "invalid id (must be greater than current id)".
This is reasonable to expect given the stack's unique role as the
arbiter of IDs: as long as there's no internal list of all IDs
currently in use (and given the compact size of stack files I certainly
don't mind that there isn't), if you could set the stack ID lower you
would risk creating a new object whose ID would conflict with an
existing one.
