Customers able to buy over the quantity while stock management enabled

Just posted in an archive forum at the link below but not sure if that is still viewed.

Basically if two customers come in at the same time and order over the stock quantity between them they are still allowed to pay based off my testing.

 

Example:

Stock QTY of 3

Customer 1 orders 2

Customer 2 orders 2 at same time

Both customers can pay but only have 3 products instead of 4. 

 

It seems to be as long as the products are in their cart they can check out. 

 

I have enabled stock management and my payment gateway is PayPal Europe, I also use 1 page checkout.  Has anyone found a solution to this yet? I will be selling high priced items with potential to have high demand for small quantities.

 

Is there a way around it?
