Right. I intended that to be a heads-up in both directions:
it is not simply a library convenience function, so one needs
to think about when to use it. In particular, it's possible

create additional system load instead of reducing it.
Can you say more about this? I assume that sending static
images back and forth is a good fit for sendfile().
Your previously stated use case sounds like a good fit. I can easily
imagine sendfile() implementations starving other network operations,
though (and IIRC linux's early sendfile() implementation did so).
It's essentially an optimization specific to web servers.
