Hmm. It might not be an actual leak per-se... I've noticed in busy areas 
that the viewer will often hit a *lot* of parallel HTTP texture fetches. 
I'm not sure if there's a hard limit there, because my texture console 
can easily overflow with active texture-fetches. That's... what... 30+ 
and I'm guessing a minimum of two file-handles each right there (and gut 
feeling says there's probably closer to 3 involved).

If there's no cap on the number of parallel HTTP texture fetches (or the 
cap is too large), then you'll see more simultaneous fetches for 
higher-latency users (as an artifact of each HTTP session taking longer 
to complete), all other things being equal. If that is the case, then 
it's likely to have a far lower incidence if you're on the continental 
USA. Altair... you're in southern Europe, right?
