hash() yields different results for different platforms

[Kerry, Richard]

The hash is not expected to be unique, it just provides a starting point
for another search (usually linear ?).  

See http://en.wikipedia.org/wiki/Hash_function


Helpfully,

Richard.

If the hashed should be unique, 32 bits is much too low if you have
millions of entries.
