Comment(by mderickx):

 By the way, the best way to do solve these tickets is probably to write a
 cython "matrix_from_list_of_iterables" command and call that from the
 vector initialization, but I don't know if that would be worth it since
 most methods done on matrices will still be way slower than initializing
 them. I.e. this patch makes sure that initializing is no longer the bottle
 neck.
