Comment(by tornaria):
For the record, this is what I think could be used for mod2 sparse via
dense:
{{{
dense = self.dense_matrix()
dense.echelonize()
self.set_block_unsafe(0, 0, dense)
}}}
The last step does the conversion from dense to sparse, and it's way
faster than calling dense.matrix_sparse(), but it's still slow.
