    we might still want to synchronize to avoid multiple concurrent calls to client.getData(),

> Currently, SharedValue has limited utility as the internally managed version is always
used for trySetValue. A good improvement would be a) add an API to get the current value AND
current version and b) add an alternate trySetValue that takes a new value AND an expected
version.
