Can Zen Cart shopping cart "reserve" store items for fixed amount of time?

Decrement needs to fail if inventory is zero, and return a failure code as well.

It usually does and if customer_2 was on any other page except checkout_confirmation (final step before placing the order), they'd be redirected to the shopping_cart page with a notice the product is currently out of stock. IMO, it's just the existing stock check logic that should be added to the checkout_process module that runs just before the order is created.

20 years ago I wrote an entire store from scratch in Perl + SQL. I just don't have time to do it again and maintain it in PHP.

As you're probably aware, checks aren't enough. You need SQL or some other gateway to negotiate access to the inventory data.
