If the serialized form change is a problem, that part can probably be 
reverted - it's far less likely that a single compressed stats chunk will 
overflow Int.
The bug I hit was in the global rank counter part, and I changed the other 
part just by reviewing the code around for other places that could conceivably 
use a Long instead of Int.

Seems reasonable; @clockfly what do you think?
The serialized form changed here, but I'm not sure we'd guarantee 
compatibility there. This isn't something serialized to files for long-term 
storage is it?
