[Typo3-shop] orders go crazy!

[Stefan Beylen]

Hello Shoppers...

something strange is happening here. On every order I make the rows in 
sys_products_orders get more, and I mean not one by one but there are 
several new rows (I guess for every click in the shop one) inserted all 
empty just with the deleted flag set to 1...so after maybe 10 testorders 
the uid of my orders increased to 730

is this a bug or on purpose ;)
thx
