 I have a lot of channels to auto-join on connecting.

 It was okay when I connect to Freenode at the first time.

 If there is any ping timeout and Pidgin tried to reconnect, Freenode kick
 me with Excess Flood.

 This problem can be replayed every time I reconnect.

 I sniffed the packets with Wireshark and saw Pidgin send a lot of "JOIN
 #xxxx \n JOIN #xxx" at the same time, which caused Freenode server to kick
 me.

 I suggest that Pidgin use "JOIN #xxx,#xxx,#xxx" to reduce network traffic
 or add some delay between sending a huge amount of "JOIN"s.
