hi Maxim,

yes, attribution in CHANGES.ru would be great, thanks!

One comment on changeset 4872:

On line #1385, wouldn't you want to call ngx_resolver_rotate()
instead of ngx_resolver_dup() ? To cover the case of the name
not being cached at all for some odd reason - like, if TTL is set
to 0 seconds. Or, if TTL is really small, which would also skew
the distribution to use the 1st addr a lot more than others.
