Assuming that you'll get a steady flow of customers, you could clean
up the list of active carts every time you create a new one. Offhand,
I'd use a timestamp for each cookie, and keep an index on the time
stamp. That should make it quite fast to find all timestamps older
than a certain time. (Assuming that an index is necessary at all --
try it without one first, and see if it is fast enough.)
Since you're inserting a new value into the table at this time, you're
going to have to lock the table (or at least a part of it) anyway, so
cart+cookie creation time seems a good time to cull old cookies.
