No, I was exaggerating for effect.  You can outrun the capacity of any
reasonable repository of Cokes long before the Gnab Gib arrives.  More
to the point, doing two GETs on such an URL delivers two distinct Cokes,
not merely two copies of the same pile of bits.  As others have pointed
out, this use of GET is unsafe.
