  It is NOT clear.  Simply because bulk flow is very slow does NOT
mean there is none.  It is conceivable that bulk flow would
be slower than the diffusion effect you mention.  But you
haven't shown that at all.

  Corn syrup, though very viscous, does slump through bulk flow, even
when it has been in the freezer (i.e., has been supercooled.)  You
seem to have assumed that super-cooled fluids don't flow.  I
challenge this.
