this findPair becomes really slow.

Either sort the list to speedup the query, or use a different solution. It is mainly used for Removing overlapping pairs. Removal could be delayed. we could keep a linked list in each proxy, and store pair in one of the proxies (with lowest memory address) Also we can use a 2D bitmap, which can be useful for a future GPU implementation
