Large file (>1G) causes PyWall INPUT queue to get booted

[llcopeland]

For some reason, transferring large files on my Ubuntu 14.04 machines causes PyWall to get booted from the first queue without C-cing. I ran sudo ./main.py example.json -f pywall.log and then a wget bertha.case.edu/vivid-desktop-amd64.iso. From the log:

 Tore down IPTables: iptables -D INPUT -j NFQUEUE --queue-num 1

This has not been reproduced on machines that don't belong me. However, I think we should document this in our report as a limitation.
