Bug#494768: sendfile bails out with error

[cfeller@rocketmail.com]

Stephan,

I tried a few at random:

    linux-image-2.6.24-etchnhalf.1-amd64 2.6.24-6~etchnhalf.5
    linux-image-2.6.25-1-amd64 2.6.25-1
    linux-image-2.6.25-2-amd64 2.6.25-6
    linux-image-2.6.25-2-amd64 2.6.25-7

and none of them resolved the problem.  This is a bit troubling to me.  

Are there any other (apache2) dependencies that could be to blame?  
Specifically I'm wondering if sendfile() was always broken, but if
apache2 was not previously attempting to use sendfile()...  Stephan - 
you said that not much changed in the apache2 or libapr code to break 
sendfile().  Does apache go directly to the kernel or does it go through 
libc for instance?
