Comment:
I can't believe that we never cached heights before! (Perhaps we did when
they were only implemented over QQ, but I'm not going to go back and
check).
Note that this is one case where the caching is slightly less trivial
since we need to recompute of the desired precision is > the cached
precision. The patched code does that properly.
Applies fine to 4.4 and all elliptic_curves tests pass.
