Comment (by jinmei):

 trac2060 is ready for review.

 Actually the only related change is the first commit (d73842e).

 But since it's pretty small I wanted to piggy back one outstanding
 issue described in #1767.  It's the second commit (e0ce6d2).
 The diff for this commit is a bit large, but what it does is
 essentially simple: introduce a generic derived class of
 ZoneFinder::Context, reducing the overhead of constructing the base
 class, and have most of the others (except in-memory) use the generic
 one.  I decided to not to make the base class fully abstract (it still
 has member variables and non pure virtual methods), considering the
 balance between design purity and convenience.

 I hope the additional review load for the second commit is acceptable,
 but if not, I'm okay with deferring it to #1767.

 No changelog is planned for this ticket.
