  I have a feeling the startup time is hugely dominated by disk IO (to
more or less degree depending on your hardware), and unfortunately
renicing a process only affects CPU, not disk IO (right?).  It's a pity,
really.  I wish Linux could give different disk IO priorities to
different processes depending on "niceness"...

  Still, renicing the process couldn't possibly hurt either.
