It doesn't matter (in engineering terms) whether stuff that reaches the 
event horizon goes somewhere else or not (that's kind of the definition of 
an event horizon).  But an accretion disk outside the Schwarzschild radius 
is just standard dynamics for any super-condensed object.  At a distance of 
several Schwarzschild radii, Newtonian physics will be reasonably accurate 
(albeit not in detail).
