Comment:
For the record: Today I slightly improved MeatAxe matrix initialisation
(my MeatAxe wrapper relies on a modified/improved version of
MeatAxe-2.2.4, and today I added memset).
Now, multiplication of two random 2000x2000 matrices over GF(3) takes 1.72
seconds with MeatAxe (it used to be 11 seconds, without memset), compared
to 1.65 seconds with _multiply_linbox and 8.34 seconds with plain Sage
matrices.
I really wonder why linbox isn't used by default.
