Comment:
I will not claim the current code to be perfect, but what you suggest is
not better.
We want to have a specific, well chosen URL we use for the general backend
healthy check, to avoid having one randomly failing URL take down the
entire backend.
The saint-mode facility, contains a limit, so that if more than
$saintmode_threshold different URLS fail, the entire backend will be
declared unhealthy.
