I'm confused be the response I get to the attached program.
In a nutshell, I'm building a reader, attaching it with addReader, later
removing it with removeReader. And I'm getting this:
time python test_reactor.py
Traceback (most recent call last):
Failure: twisted.internet.error.ConnectionFdescWentAway: Uh:
Filedescriptor went away.
Which seems to be telling me that I don't know as much yet as I'd hoped.
Why would the reactor care about a closed file descriptor that isn't
even in it's interest set?
