It does not for SH (and DH I presume but I never tested that). Well, not as
expected at least. As I've been pointing out for well over a year and just
re-tested with the latest kernel.
If the weight goes to 0 with SH and quiescent=yes set connections will
keep going to the old server as expected. Alas even when they expire they
will keep being sent there as will completely new connections if the hash
result assigns them to the weight 0 RS.
