+;; before disconnect, server usually sends something like
+;;
+;; Closing Link: nick[ipaddr or hostname] by servername (reason)
+;; some other reasons are: "G-lined", "K-lined", and "Your host is
+;; trying to (re)connect too fast -- throttled"
+;;
+;; reconnect should wait 30 sec depending upon the throttle
+;;
+;; avoid too many reconnect messages in the logs
+;;
+;; grep'ing around the net-nittin-ir source, it looks like 361
+;; rpl_killdone and 362 rpl_closing may refer to the closing link
+;; error i mention, as in, modern ircds may use numerics for such
+;; logging of unhandled numerics is good to do also
