I can imagine that happening. Consider a scenario where complete 
starvation is considered a Really Bad Thing.

if (firefox) {
    // higher priority channels will completely starve out lower 
priority ones. Don't.
   priority = normal
} else if (chrome) {
    // lower priority channels will get some packets through. That's OK.
    priority = high
} else {
    // I have no idea what will happen, let's play it safe.
    priority = normal
}
