Orphaned SIDs shouldn't happen.  Disabling accounts, ok, but removing
them?  I don't know.  So the question is, if there's no account with
these SIDs anymore, why aren't these SIDs removed from the ACLs?
It's not only Cygwin.  These SIDs also unnecessarily slow down each
single access check of the OS.
