Here's a few things I tried to write output to a python subprocess pipe.

from subprocess import Popen, PIPE

p = Popen('less', stdin=PIPE)
for x in xrange(100):
    p.communicate('Line number %d.\n' % x)

crazyguitar

import subprocess
import select
from sys import exit

p = subprocess.Popen(['python3', './subproc.py'], stdout=subprocess.PIPE)
e = select.epoll()
e.register(p.stdout.fileno())

while True:
    events = e.poll(1)

    A class to implement read-write locks on top of the standard threading
    library.

    This is implemented with two mutexes (threading.Lock instances) as per this
    wikipedia pseudocode:
