Comment(by cremona):

 OK, so I was the one who put in those two breakloop calls, which I only
 did since otherwise things did not work properly -- but in the testing I
 just did I found it only necessary to delete the brealoop call in
 {{{__init__}}}, while keeping the one in {{{_start}}}.  Are you both sure
 that it is safe to delete the one in {{{_start}}} as well?  Does that not
 cause gp to enter the breakloop on encountering an error, which is not
 what you want?

 If you are right (and I assumed that you did test this!) then I am
 wondering what else has changed, since when we started the pari upgrade it
 was definitely necessary to deal with this.

 And by the way, the *only* reason I created a {{{_start}}} function for Gp
 different from the default one in PExpect was to add this line in
 {{{_start}}};  so if that line is not needed, you can probably delete the
 while {{{_start}}} function for class Gp.
