    Remove some outdated iprop documentation
    
    Commit 969331732b62e73d1e073ff3ad87bf1774ee9fd1 (ticket 7369) removed
    the code to return UPDATE_BUSY if the database was modified within the
    last ten seconds, but did not remove the corresponding documentation
    text.  Remove it now.
    
    (cherry picked from commit 16c3a5917a8fd2706a1e1b2e5a58e1319f8fa8f7)
