Comment (by jdemeyer):
After looking at the PARI 2.6 sources, I think the best solution for Sage
would be to use the (admittedly undocumented) variable `iferr_env` from
PARI. Because the `pari_CATCH` stuff is re-doing a `setjmp()` call which
Sage's `sig_on()` already does. This is bad, for example for performance
reasons (I made a lot of effort in making `sig_on()` fast).
