There are at least two quality hash_map's available besides the SGI 
implementation.  I think it would behoove the C++ community to try and 
use each of these versions to the extent practical, instead of just 
SGI's.  By doing so we may discover things that are good and bad about 
each version, thus ultimately contributing to a better std::hash_map.  If 
only the SGI hash_map is exercised, then we have greatly decreased our 
experience.
