Is there some sort of critical angle limit that prevents it 
from  going to 1.0? Wouldn't 1.0 = a full quadrature sweep?

The problem might be in some rounding that tab does, because as I said  
before and now
confirm, phasor will not go to 1.0 at all. Here is the code excerpt  
that tells us that (ugens2.c, 147):

         if (UNLIKELY(phase >= 1.0))
           phase -= 1.0;
         else if (UNLIKELY(phase < 0.0))
           phase += 1.0;
