    Allow flag watching while synchronizing folder in background
    
    Previously, synchronizing folders caused a jump in CPU, so work was
    done to minimize activity.  Optimizations to folder normalization
    has reduced the CPU load, so it's okay now to allow flag watching
    while the background folder is open.
    
    This is not a substitute for an architected solution: periodic
    flag synchronization with folders, not merely when changes in contents
    (additions/removals) are detected, but this helps some, especially
    with high-traffic folders.
