Well, this one can be configured per service by changing the scheduler.
Or are you concerned about the fact that the code for SHP and SH is
essentially the same and should be merged?

I don't think a global sysctl is a problem for sloppy TCP (SCTP). I
think it's unlikely that you'll want to enable it on one service but not
on another.

This isn't a bad idea, and it will probably find other uses, too.
Is there a reason why the SH fallback behaviour shouldn't be default?
That is, is there a reason why the current behaviour (client connection
gets reset if it is directed to a realserver with weight 0) is
desirable?

I'll take a look at the latest version.
