Problem with hashing

[Sirorezka]

New version of 'hash' in python give different values during execution of each thread when doing multiprocessing. Following error will accure:

50000_firms/start.py return error when running in 2 or more processess:
KeyError: ('myagent', 11980)

There is problem with three functions which use 'hash':
multiprocessing.py -- def insert_or_append
multiprocessing.py -- def do
agent.py -- def _send_multiprocessing

my proposal - replace default hash function with:

import hashlib
def new_hash(agent_key):
    return int(hashlib.md5(str(agent_key).encode()).hexdigest()[:8],16)

Would the variable address of the string become unambiguous across processes with id(agent_name)? Perhaps a different hashing scheme is used when multiprocessing is on.
