Settings for PYRANDOMHASH:

PYRANDOMHASH=1 enable randomized hashing function PYRANDOMHASH=/path/to/seed enable randomized hashing function and read seed from 'seed' PYRANDOMHASH=0 disable randomed hashing function Why not PYTHONHASHSEED then?

See my patch attached to the issue #13703? I prepared the code to be able to set easily the hash seed (it has a LCG, it's seed can be provided by the user directly). I agree that the value 0 should give the same behaviour than the actual hash (disable the randomized hash). I will add the variable in the next version of my patch.
