[Maxima] Does GCL or Maxima have a memory leak?

It does not give memory back to Windows for sure. I tried at the end of my process kill(allbut(List7,List8)) and then
tried to plot with draw(points(List7),points(List8)) and got out of storage error for stream. So the 340 Megabytes was
not even available to GCL and Maxima.
The lists were just 200 elements.

My guess is that GCL doesn't ever give memory back to Windows.
It just makes it available to other lisp processing.
Other free lisps will probably do the same.
