Yes. It will be good to test if `num_points=400` in the same doctest
command without this patch still leads to the massive slowdown. I can't
test it since it is apparently only visible on the solaris arch. The
command that is desired to be doctested is
{{{
sage: list_plot3d([(0,0,1), (2,3,4), (-1,-1,-1)],num_points=400) # long
time
}}}
There is one workaround (even with the resource leak) and that is to
decrease the value of `num_points` in the current patch.
