Certain HTTP requests repeatedly hang

[Robin Green]

Some examples:

* Emacs fails to update packages and always hangs on the same package - at least over the period of a few hours. A few weeks ago it was hanging midway trying to download haskell-mode, most recently it was markdown-mode.

* The sbt launcher jar can't download sbt. This is a very easy to reproduce case. It hangs straight away.

* An AJAX request on inthe.am always hangs. It's always the same URL.

I don't have this problem in a non-Qubes Linux machine on the same Wifi network. I am guessing something like a checksum handling error - maybe a certain checksum value is handled incorrectly and this is causing packets to be incorrectly dropped somewhere inside my PC.

How would people suggest I track this issue down? My plan is to start with wireshark inside the AppVM, then look at wireshark on the FirewallVM, then on the NetVM, until I find where packets are being dropped or modified or whatever the issue is.

Could it have something to do with the firewall rules you're using in your AppVM(s)?
