It is a result of the drivers sending more commands to the card then its
input que can handle, meaning that the last command sits on the bus
tying it up untill there is room in the card for accept it. All that for
maybe 1 or 2 fps more.

And software modems, which will usually disconnect. After all they are
only a fancy soundcard that connects to a phone line.
