But this isn't what happens.  The event horizon is the surface at which 
one _cannot_ stay at constant radial coordinate.  In other words, the 
required acceleration to stay at constant r at the event horizon is 
_infinite_.

That means that as you approach the horizon (from the outside, of 
course), the required acceleration to hover diverges.  To stay 
arbitrarily close to the horizon requires arbitrarily high accelerations.
