Yeah... using this approach I was finally able to hunt the leak!!!.

The problem was hidden in C code that is used to access to a C library. I'm
afraid that valgrind was unable to detect that because the underlying C
library does not call the standard malloc to create the leaking objects.

Of course, the Python reference counters were unable to detect that as well
(although some black points still remain, but not very important).

Anyway, thanks very much for the advices and encouragement!
