Thanks for the background. After playing with it some more, I'm still seeing leaks, and I think some more extensive changes will be needed to fix them (though I'm not sure what the best way to do it is). The main problem is that the TXPNode tests all of its tiles against the current eyepoint every time it's traversed and throws out tiles based on that, so with two views far away from each other it's throwing out and reloading the entire tile set every frame. I think it needs to be modified to use an expiration scheme like the DatabasePager does for its toplevel tiles, so that tiles in view of one eyepoint but not the other get marked and not thrown out.
It's also leaking half the tiles every frame while this is going on, which I don't know the cause of yet. I wasn't seeing the problem before after removing the RetestCallback because I had my target paged LOD number set very high, but it does still leak (a lot) with a smaller paged LOD target (I'm testing with 100 now). Anyway, if I get it fixed up I'll certainly submit it.
