[ Upstream commit 6c31e4c98853a4ba47355ea151b36a77c42b7734 ]
Since v4 files are expected to be long-lived, there's little value in closing them out of the cache when there is conflicting access.
Change the comparator to also match the gc value in the key. Change both of the current users of that key to set the gc value in the key to "true".
