Quantities of USD returned by the commands above are different.
If someone place an ask order with 2500 BTS and 0.003125 USD/BTS, it's likely that the short order will leave about 200 BTS in the market. Strange behavior.

Looks like it's partially fixed in 0.9.1 (after hard fork).

• quantity of USD in blockchain_market_order_book is unchanged, but if someone place an ask order with the same quantity of BTS, it will full-fill the short order. So we can say the quantity is correct.
• quantity of USD in blockchain_market_list_shorts is unchanged thus incorrect.
