Huh... on second thought, this limit applies to std::vector, but not to other 
types, since they don't have a single memory block.

That said, if you are using more than 2 GB in a container on a 32-bit system, 
you deserve the OOM conditions. Please upgrade to a 64-bit processor. They're 
only 10 years old now.
