No, no. On *Windows* there is an address space limit of about 3Gb (and on
other 32bit systems)
On a 64bit system the limit is that a vector can't have length greater
than 2^31, but this would be 8Gb for integers or 16Gb for doubles and so
represents larger objects than you would want to handle on most current
64-bit systems.
