I'm a little late to the party, but now that Python 3.4 is out and asyncio is
ready for use I started reading things like:
https://glyph.twistedmatrix.com/2014/02/unyielding.html
Which explains why the asyncio approach is the future and all the bullet points
in that article make a lot of sense.

Hi,
What is the correct idiom for getting the path to a top-level module in 3.3 and
3.4 when the module might be frozen?
At the moment I'm using this:
if getattr(sys, "frozen", False):
path = os.path.dirname(sys.executable)
else:
path = os.path.dirname(__file__)
Thanks!

Hi list,
I noticed a behavior change on Thread._stop() with Python 3.4.
I know the method is an undocumented "feature" itself, but some projects are
using it, and now they fail.
A minimized snippet to reproduce:
#!/usr/bin/python
import threading
def stale():
import time
time.sleep(100
yeah , asyncio is a great module, congrat for all jobs you are doing
