What is heating the memory here? hashlib?

I have used gc and del. No luck.

The most probable cause seems to be hashlib not correctly handling big
buffers updates. I am working in a computer and testing in another. For
the second part may be somehow I forgot to transfer the change to the
other computer. Unlikely but possible.

Anyway it is doing its job right now with bfsz=16KB (this takes a few
hours). No memory leakages anymore.
I'll address this problem in a near future, may be when I move to the
new kubuntu 16.04 LTS. This will bring new SW releases and the problem
may have been fixed.

Thanks
