  We compute the non-equilibrium stress tensor induced by a heavy quark moving
through weakly coupled QCD plasma at the speed of light and compare the result
to N = 4 Super Yang Mills theory at strong coupling. The QCD Boltzmann equation
is reformulated as a Fokker-Planck equation in a leading log approximation
which is used to compute the induced stress. The transition from nonequilibrium
at short distances to equilibrium at large distances is analyzed with first and
second order hydrodynamics. Even after accounting for the obvious differences
in shear lengths, the strongly coupled theory is significantly better described
by hydrodynamics at sub-asymptotic distances. We argue that this difference
between the kinetic and AdS/CFT theories is related to the second order
hydrodynamic coefficient $\tau_\pi$. $\tau_\pi$ is numerically large in units
of the shear length for theories based on the Boltzmann equation.
