Yes, this isn't a problem at all. In fact, the theoretical limit is 
many Tb. All sizes are represented by 64 bit integers, so there's no 
4Gb limit anywhere. Additionally, store size is measured in blocks 
rather than bytes so that means 64 bits can represent a huge amount of 
data.

I think it's a compiler bug I'm trying to trace, and it just shows 
itself as a the size of the store being repeatedly "corrected". 64 bit 
arithmetic is not trivial for compilers to output on 32 bit machines!

Thanks,

Ben
