Seems to be.  I can reproduce a massive compile-time difference (up to a 
50% increase) between 108479 and 108480, but I'm having trouble figure 
out where exactly that time goes.

Joern, please revert the patch for now.  I'll be away for three weeks; 
if no one else works with you on this in the meantime I'll help once I'm 
back.
