I wasn't able to find any documented upper limits on retain count on 32-bit machines (or in general). I am interested in knowing this because I foresee a situation where I may have objects with retain counts of hundreds of millions of billions and more.

"hundreds of millions of billions"? How much is that?

If "hundreds of millions of billions" is 1e17 and if a retain operation take 1 ns to complete, it would take over three (3) years to send all those retain messages...

(if I didn't make any mistakes with the calculator - it's been known to happen...)

I humbly propose that:
a) Your design is wrong, or
b) Cocoa+ObjC is not the right set of tools to solve your problem, or
c) some sort of combination of the above.
