You can do this right now with Python 3.2+ and concurrent.futures:
from concurrent.futures import ThreadPoolExecutor
from functools import partial
import time
class DoSomething:
 a = 4
 b = 2
 c = 1
 def add(self, prop, val):
 cur = getattr(self, prop)
 time.sleep(cur)
 print('Adding %d to %s' % (val, prop))
 setattr(self, prop, cur + val)
 def __init__(self):
 with ThreadPoolExecutor(max_workers=3) as pool:
 pool.submit(self.add, 'a', 1)
 pool.submit(self.add, 'b', 2)
 pool.submit(self.add, 'c', 3)
 print(self.a, self.b, self.c)
DoSomething()
Here we call 'ooo' the ThreadPoolExecutor context manager :)
