Old description:

> In `devel/sage/sage/matrix/matrix_integer_dense.pyx`, wrap IML calls in
> `_solve_iml()` in `sig_on()`/`sig_off()`.

New description:

 In `devel/sage/sage/matrix/matrix_integer_dense.pyx`, wrap IML calls in
 `_solve_iml()` in `sig_on()`/`sig_off()`.

 The patch also changes the exception type for non-square matrices from
 `ArithmeticError` to `ValueError`, since that's just a limitation of the
 implementation, it's not a mathematical obstruction.
