So on reading this is does not appear that you have a memory leak, but
that you are using too much memory, ie the total memory consumed by
your 15 open figures is dragging your system down. But when you close
the figures, the memory usage cycles back down. Eg you started and
ended cycle 1 with about 70M consumed, and peaked around 150M.
Is this an accurate description of your problem?
There are definitely areas where we can and should improve memory use,
but this would have to be handled on a case by case basis and would in
some cases be backend dependent.
