Replying to [comment:29 pbruin]:
> Of course, for signal handling you are stuck with the slow version
False :-) Sage's `sig_on()` uses `sigsetjmp(env,0)`. It manually resets
the signal mask when actually handling an error.
> Finally, the discussion cited above mentions the idea of letting the
user of the PARI library specify a function to call when an error occurs
instead of the `setjmp()/longjmp()` construction.
I think this would be very good for Sage. I personally wouldn't mind
patching that in ourselves in the Sage version of PARI.
