Old description:
> When reproducing this, make sure to wait about 10 seconds before trying
> to interrupt, as it takes time earlier in the function elsewhere, which
> handles the interruption properly.
New description:
{{{
sage: M = Matrix(ZZ, 300, 300, sparse=True)
sage: B = M._mod_int(7)
sage: B
300 x 300 sparse matrix over Ring of integers modulo 7 (type 'print
B.str()' to see all of the entries)
sage: B.parent()
Full MatrixSpace of 300 by 300 dense matrices over Ring of integers modulo
7
