And star implements a FIFO that is written in a way that dramatically reduces
the sawtooth behavior seen typically with other applications. You just need to
tell star to use a say 2 GB FIFO and star will be able to keep the tame
streaming for a longer time before it waits until there is enough data for the
next longer streaming period.
