I want to echo Patricia's comments and say that you still haven't 
explained what it is you are trying to do, what problem you are trying 
to solve.  This clearly describes an implementation, not the design goal 
at hand.

What do these ints ultimately represent?  Items for sale?  Customer 
purchases?  Factory assemblies?

Also, similar to Patricia, my bullshit meter is beeping loudly.  In 
fact, I see the extra large manure shovel has automatically deployed, 
and the rubber hip boots have dropped from the ceiling.  You're design 
is so obfuscated that even knowing your design goal it's likely to be an 
unmaintainable mess.  Expect to be chastised by any other programmer who 
sees this disaster.

You might want to back up and just do the obvious, like store a bunch of 
simple data objects in a synchronized collection.  I'd think that would 
be faster than what you have, as well as infinitely more maintainable.
