I think the cache is placed at the wrong level (it doesn't have to be a
GRavatar_url_cache, but can be a general avatar_url_cache).

I'm not sure about it. The URL depends on email and size (can you use
arrays as hash keys in Perl?) , and the email part might be the same
but the size part might differ across separate calls (in theory; in
practice avatars in a view are presently all the same size; but for
example if we were to autodetect email addresses in commit messages,
we might have both single- and double- sided avatars in the same
page). By hashing on email+size only we would lose the benefit of
cache when using the same avatar at separate sizes.

You could have a hash key of "$email_$size", or something similar to
fake an array hash key.
