Except that it doesn't show that, because every entity expansion 
involves copying the following text forward. I'd be astonished if that 
wins compared with delivering expansions SAX-style. I'd even be 
surprised if it wins against non-in-place expansion to a separate 
buffer (assuming the copy was optimized away for the no entity refs 
case).

Cheers,
