> I would be curious about the soft reference implementation as in
DetaIteration cases I think it is a valid situation that the job needs less and
less memory. Please add the licence header to the manual test file.
This is my first attempt to use a "soft reference pool":

I could not measure any performance gain compared to the code before this
pull request as a baseline. Hopefully I will have some extra time tomorrow, so
I can further investigate whether there is something wrong with my first
implementation or the approach.
