Simple question. If I have the following code:
class A:
def __init__(self, s):
self.s = s
self.m2 = m1
def m1(self):
pass
if __name__ == '__main__':
a = A("ads")
a.m1()
a = None
The object is not garbage collected, since there appears to be a cycle

Howdy,
Is there any way to attach to an already running process by pid? I want to send
commands from python to an application that is already running. I don't want to
give the command name to subprocess.Popen.
