There is a race window between the two, with no guarantee that there
hasn't been any modification between the two.

Also, if there is proxies involved the situation gets even messier, and
it's possible the GET gets executed before the PUT is complete, or might
even get the old entity from a cache somewhere. While the PUT
invalidates the caches the PUT goes via, there is no guarantee the GET
will travel the exact same path..
