Comment(by vbraun):
I've now added sig_on/sig_off blocks around expensive library calls.
Interrupting works, too:
{{{
sage: Cone(random_matrix(QQ,100,10).rows())
^CERROR: An unexpected error occurred while tokenizing input
The following traceback may be corrupted or invalid
The error message is: ('EOF in multi-line statement', (2152, 0))

Note: in this example I have #10140: "Base sage.geometry.cone on the Parma
Polyhedra Library (PPL)" applied.
