I tried to put Environment object in memcache, but it's not picklable so no joy. FileSystemLoader can be pickled and cached, but for some unknown reason cached object throws IOErrors if template code changes (eg. because of new deployment) and I did not found a way to remove it from cache after succesful deployment (and do not have key versioning yet).
I ended up creating module-level environment object and hoping the module will be kept in module cache fo long enough to be reused.
