I think he measured it across the call:

  start 
  CharNextW
  end

but it still doesn't add up. If his measurement is correct, we certainly
have a high (it's an understatement, IIRC a syscall on Linux is on the
order of a few us) call overhead. Maybe a bit of disassembly might help, 
but I can't imagine what could have gone wrong in such a trivial of a case.
