New submission from Charles-François Natali:
This patch is an attempt at making pickle use Modules/hashtable.{h,c} instead
of its hash table ad-hoc implementation for its memoization table.
I'm saying attempt, because although it works correctly, some benchmarks are
actually slower.
I didn't profile it, so I don't know if it's due to the hashtable
implementation, function call overheads, etc.
If we manage to bring this on par with pickle's ad-hoc implementation, it would
probably be interesting to replace it. If not, then we can just drop this patch
:-)
Also, there might be other places in the code base which might benefit from
this generic hashtable, maybe.
