An example for very slow fetching from positive characteristic to characteristic 0

[steenpass]

> ring s = (536870909,t), (x,y,z), (C, lp);
> ring r = (0,t), (x,y,z), (C, lp);
> list @l = list(ideal(-z+(t3), -z+(t2), z+1, z-1, z), intvec(1,1,1,3,8));
> setring s;
> int t = timer;
> list @l = fetch(r, @l);
> timer-t;
50
> @l;
[1]:
   _[1]=-z+(t3)
   _[2]=-z+(t2)
   _[3]=z+1
   _[4]=z-1
   _[5]=z
[2]:
   1,1,1,3,8

The result is what I expected, but why does it take 50 seconds?
