Okay, just for clarity's sake: the ^s character tells the terminal
to suspend itself until it receives a ^q character (which tells it to
continue - a very useful keystroke to know if you've hit ^s by mistake).
The net result is that whatever programs are trying to write output to the
screen are going to block (i.e., stop and wait) during their write(2)
calls once the (dunno what size for linux console, but relatively
small) terminal buffer fills up, until you hit ^q in order to relieve
the traffic jam.  (Picture a highway with a roadblock: once cars fill
every inch of road on the highway, anybody else who tries to get onto
the highway will have to just sit and wait.)
