Comment:
The messages in the ticket description
{{{
^CException KeyboardInterrupt: KeyboardInterrupt() in
'sage.combinat.designs.orthogonal_arrays_find_recursive.is_available'
ignored
}}}
show that the issue is not just `sig_on()`/`sig_off()` but also missing
`except` clauses in `cdef` functions, see also #16233 for how to fix this.
Also, your codes mixes Cython and Python, so I would go with
[http://www.sagemath.org/doc/developer/coding_in_cython.html#using-sig-
check sig_check()] in the inner loops which is much safer than `sig_on()`
and `sig_off()`.
