Commands in order:
- `futurize ./ -w -n`
- git grep -l "queue\.Empty" | xargs sed -i 's/queue\.Empty/queue2k.Empty/'
- git grep -l "queue\.Queue" | xargs sed -i 's/queue\.Queue/queue2k.Queue/'
- git grep -l "import queue" | xargs sed -i 's/import queue/import queue as queue2k/'
The search and replaces are needed because the local variables named
`queue` break the module that is called `queue` instead of `Queue` in
Python3
The testcases all still pass with python 2 but with python3 break
completely due to pwnlib issues
