qsort is history :}. The list.h template uses an insertion sort.

I've already though about this:

What you should do is have all the sites pinged when parsing
mirrors.lst, and then store the resulting list and times for future
reference on disk.
Then in the site_list_type_constructor add a ping parameter, and pass it
the ping. It should prepend the stringified ping to the sort key, giving
the user a list of fastest->slowest sites, and meaning that all the
linear code will automagically hit the fastest site first.
