Davi-

   Regarding this issue:

	http://people.apache.org/~davi/leopard-sendfile.c

   Our kernel folks say this isn't a bug:

	No, this is not a bug.  Our sendfile(2) implementation is
	similar to FreeBSD 4.x, where the 4th argument to the system
	call (the value-result length parameter) includes the header
	length.  In FreeBSD 5.x, this length does not include the
	header, but that is not the semantics followed by Mac OS X.

   Is this sufficient information?  I've still got the bug open until  
I hear from you.
