You've just given the main reason why, I think.  I guess the demo should
be changed along the lines of animate.dem, i.e. limit the reread loops by
a counter, and possibly introduce a pause to make it possible to see
something.

I suspect the same applies to enhancedtext.dem --- they test features that
are not known to either be available or fail seamlessly, on all terminals.  
Ethan, these were introduced by you: any comments?

We've discussed this, but never reached a conclusion.  all.dem should 
probably be generated by 'configure' anyway.  But putting unrealiable
stuff doesn't really work, not as long as 'make check' expects to run
all.dem on the default terminal and expects it to succeed.  I.e.
at the very least, we'ld have to have two copies of all.dem: one for
feature demonstration, the other to be used by "make check".  The
latter would have to make sure it only uses features that don't
cause gnuplot to error out.
