Just realized the patch in the previous message was not
in the most-readable form... Here is the shorter version of the diff
with new files omitted. (If anyone's interested, you can see the new
files in the full diff, attached to the original message. These files -
ngx_http_upstream_random.h and ngx_http_upstream_random.c -
are, for the most part, pretty much copies of ngx_http_upstream_round_robin.*,
with some slight changes).
