Comment (by nbruin):
Not introduced by this patch, so shouldn't be held against it, but ...
{{{
RealIntervalField_cache = {}
}}}
Is a strong cache! So `RealIntervalField`s get nailed in memory. That's a
very good argument for ensuring that "increase precision" leads to a very
predictable and sparse list of precisions, to minimize the costs from
this.
