I don't know when arrays stop being as performant as one could wish. For 
a problem of this size, it seems to me that one may want instead to use 
a database, such as sqlite, or a stronger beast? I expect it'll make 
your code more readable, too.
Is there a particular reason to not make the jump to a database?
