My only concern is that, if there happens to be a transient acl issue when
initially accessing the file, we will never see it in the application list even
when acl is fixed : without a SHS restart.
Wondering if the clean interval here could be fraction of CLEAN_INTERVAL_S
- so that these files have a chance of making it to app list : without much of
an overhead on NN.
