Question:How to produce animation in Threads?

In the worksheet below I produce a sequence of frames for an animation by distributing the task into several threads.  The result has strange artifacts as we see in the sample.  The artifacts vary randomly from run to run.  Am I doing something wrong?

Draw a simple picture:

> 

frame := proc(t)
  plot(x^2 + t, x=-1..1, title=typeset("t = %1", t));
end proc:

Generate a sequence of pictures:

> 

frames := Threads:-Seq(frame(t), t=0..1, 0.05):

Animate the sequence:

> 

plots:-display([frames], insequence);
