Out of memory errors with lots of products + lots of options #5203
Description
With a catalog of 300+ products & 500+ (!) options, the system runs out of memory when:
- posting form to edit product
- deleting a product option
Probably there is a memory leak in PostSoftDeleteSubscriber. A proper fix would be to process the operations asynchronously.
Also, we should avoid completely ProductOption objects in ProductType form.
