As an aside to some the Big Bang theory is being dropped or at least the  
part where it derives from a singularity is.

There's inflationary theory (or theories) by which a quantum fluctuation  
inflates.

String theory (or the over-riding M-theory) whereby any attempt to  
compress an object beyond the Planck length will result in it expanding.

and Brane theory in which our universe is caused by either a collision or  
merging of two (or more) multi-dimensional 'sheets'.

All remove the need for a singularity.

As for your initial question, the calculations for the Schwarzschild  
radius don't apply to a rapidly expanding mass. As you put it the  
expansion out-runs the gravitational curve.
