I cannot reproduce your issue. What is your exact Python version and OS?
I tried to run 100 threads calling 100 times platform._syscmd_uname('-p'). I
didn't reproduce the issue on Python 2.7 or 3.5.

import platform
import threading
def test():
for x in range(100):
p = platform._syscmd_uname('-p')
threads = [threading.Thread(target=test) for n in range(100)]
for thread in threads:
thread.start()
for thread in threads:
thread.join()
