In fact, it is important that the PlotJoined->True option should not
show the points. I am not sure why, but all of my attempts to use
MultipleListPlot for large data sets (>4000 points) have failed due to
the inability to get rid of the points: all plots look like
millipedes :(

Can anyone help with this? At present I have to use multiple ListPlot's
with DisplayFunction->Identity, combined with Show.  MultipleListPlot
just isn't flexible enough, unless I am missing something.
