 polynomial.  In Tim's experiments the current scheme ran faster, produced
 equally good collision statistics, needed less code & used less memory.
 
-Theoretical Python 2.5 headache:  hash codes are only C "long", but
-sizeof(Py_ssize_t) > sizeof(long) may be possible.  In that case, and if a
-dict is genuinely huge, then only the slots directly reachable via indexing
-by a C long can be the first slot in a probe sequence.  The probe sequence
-will still eventually reach every slot in the table, but the collision rate
-on initial probes may be much higher than this scheme was designed for.
-Getting a hash code as fat as Py_ssize_t is the only real cure.  But in
-practice, this probably won't make a lick of difference for many years (at
-which point everyone will have terabytes of RAM on 64-bit boxes).
