Comment(by mpatel):

 Jeroen's patch is definitely better than mine.  Thanks!

 Whether I run the doctest above or run `genus2reduction` directly from the
 shell and press ctrl-c/d, the program quits with no core dump.  Evaluating
 `genus2reduction.console()` in the Sage console and pressing ctrl-c/d
 returns me to the `sage:` prompt.  Also, running the long doctest suite
 passes without reproducible failures and leaves no relevant cores.

 `Genus2reduction_expect` in `genus2reduction.py` still uses its base
 class' `Expect._quit_string`, which returns "quit", but I think we can
 leave that alone(?).

 Are there any objections to making a new spkg here with Jeroen's patch?
 If we do, we should put `genus2reduction.c` under version control.
 Although I'm averse to putting too many logically different spkg changes
 in one ticket, I'll understand if we roll the changes here into #9591 and
 make this ticket a virtual blocker for an otherwise PARI-focused Sage 4.6.
