I've heard a few people saying it's possible to bring Meandering Towershell (after it's died) back for more than one turn somehow by using the Whip of Erebos. I haven't got any information as to how or why they think it's possible, and I'm not entirely certain it can work. But it's hanging in my mind that if it does, it is tied in to how the stack works.
Assuming it can work, my understanding of the stack means the entire process would work something like this:
You're right that it does work, but it has nothing to do with the stack, really.
A creature that is put onto the battlefield by Whip of Erebos is subject to the replacement effect "if it would leave the battlefield, exile it instead of putting it anywhere else."
The key here is "instead of putting it anywhere else." Since Meandering Towershell's triggered ability causes it to be put into the exile zone, the Whip's replacement effect doesn't apply -- the Towershell is already going to exile. Incidentally, the Gatherer rulings for Whip of Erebos explain this as well:
If a creature returned to the battlefield with Whip of Erebos would leave the battlefield for any reason, it’s exiled instead. However, if that creature is already being exiled, then the replacement effect won’t apply. If the spell or ability that exiles it later returns it to the battlefield (as Chained to the Rocks might, for example), the creature card will return to the battlefield as a new object with no relation to its previous existence. The effects from Whip of Erebos will no longer apply to it.
Yes, assuming no effects before it attacks, its own exile trigger "rescues" it from Whip's exile trigger. A similar thing happened with Obzedat, Ghost Council last season.
Assuming it can work, my understanding of the stack means the entire process would work something like this:
1) Meandering Towershell dies.
2) Whip of Erebos it back.
3) Attack with Meandering Towershell.
4) Exile it per it's rules text.
5) Whip of Erebos is unable to permanently exile it, due to it already being in exile.
6) Bring Meandering Towershell on your next combat step.
Am I right in how that works?

Yes, that's correct. Nothing stops you from using Whip of Erebos again.
Unless they kill it the turn that you Whip it back into play, before you get to attack with it (or in response to the Exile-on-attack trigger).
In that case it won't be exiled by its own ability, so it won't be able to return and will be stuck in exile.
