Comment(by mikeperry):

 Back to the topic at hand: It looks like
 WebSocketChannel::ApplyForAdmission() is our culprit.

   // Websockets has a policy of 1 session at a time being allowed in the
   // CONNECTING state per server IP address (not hostname)

 What a joke. I'm really tempted to make this always return NS_OK.

 I did a quick audit for other sources of DNS leaks in the rest of the
 Firefox source tree and did not find any (unless there are hardcoded
 platform specific haxx, but it looks like everything runs through
 nsDNSService, which in turn relies on nsHostResolver).
