Replying to [comment:41 pbruin]:
> There is the callback function `cb_pari_handle_exception`
The problem with that callback is that it is called after printing the
error message. For Sage, we don't want the error to be printed.
My approach would still use a `longjmp()` to jump to the `setjmp()` inside
`sig_on()`. It would avoid an additional `setjmp()` call for PARI.
