Increasing the size of a hash table would be prohibitively 
expensive. You need a data-structure that can grow gracefully.

This is more an OS issue than a language issue. Although it could 
boost high-level numeric-oriented languages and functional 
languages that cache expensive computations.

Low level languages are pretty much in the same boat.
