Description
Migrated issue, originally created by lxyu (lxyu)
do dogpile.cache have this feature yet:
one thread refresh the cached value while others directly return the old?
so I can update the cache in the background without slowing down the response time.

Research direction
The requested entry point is decorated_fn.refresh(*args); first inspect how decorated_fn currently handles cache reads and refreshes. Done means one caller can refresh the cached value in the background while concurrent callers return the existing value without waiting, with tests covering that behavior.
