Thank you, I'll have a look and will try to compare.

memory management is the main advantage of `mpz_t` over `mpn_*` when you
are dealing with nonnegative integers (hence my first question).
Now I understand what you mean by your statement that I did all memory
management by hand: I am not using `mpz_init` but `mpz_init2`, telling
exactly how many bits I will need. I found that it has a noticeable impact
on performance, since otherwise re-allocations will happen internally.
