I did some more digging. I reworked the put routine itself and changed the
growth strategy to be as aggressive as the original appender. This got me down
from a 52% slowdown, to a 20% slowdown. I've still have more work to do, but to
put this into perspective, a 20% slowdown is equivalent to adding an extra if
conditional to the put routine. 
Again, thanks Vladimir for these benchmarks.
