I get unexpected behavior from Condition when using a Manager. I expected that if I call Condition.acquire() in one thread (or process) and then call .acquire() if another thread (or process) without first releasing the condition that it should block. However it seems like Condition.acquire() never blocks... 

from multiprocessing import Pool,Manager
import time

def f(x):
    cv,t=x
    cv.acquire()
    print(t,"Got cv")
    return 

if __name__ == '__main__':
    m=Manager()
    cv=m.Condition(m.RLock())
    p = Pool(5)
    print(p.map(f, [ (cv,x) for x in range(10) ]))
