Name an implementation of std::vector that doesn't do this.

In this case, you'd do that to avoid the need for a separate COUNT(*) 
query.  If you have a pretty good idea already how many records to 
expect, reserving that amount plus some small fudge factor will probably 
run faster than doing two queries so you can reserve only exactly what 
is required.
