 In pidgin 2.10.1 for windows, from time to time ui becomes annoyingly low
 responsive while chatting on irc channels, specially in large ones like
 Freenode's #ubuntu (more than 1000 users). CPU is fully used and debug
 window reports it is performing the "periodic who" for each channel. List
 of channel users behaves oddly too when such periodic routine is
 triggered.

 [https://bugs.launchpad.net/ubuntu/+source/pidgin/+bug/856631 Ubuntu 11.10
 has workarounded it] and is delivering a modified version of 2.10.0 with
 their patch applied.


 == Patched Windows installer ==

 [https://github.com/downloads/renatosilva/pidgin/Pidgin%202.10.1.P14955%20Setup.exe
 Pidgin 2.10.1.P14955 Setup.exe]

 [https://github.com/downloads/renatosilva/pidgin/Pidgin%202.10.1.P14955%20Offline%20Setup.exe
 Pidgin 2.10.1.P14955 Offline Setup.exe]

 This is a Windows installer for 2.10.1 with the same fix used in Ubuntu.
 It works just fine for me, I can enter big channels and I don't notice any
 high cpu usage, crazy channel users list or periodic low responsivenesses.

 It was a bit more trouble than shown here: http://i.imgur.com/kbMEc.png,
 but it's fine now.
