 Pidgin doesn't play "message sent" sounds if the messages are sent in
 rapid succession (about two per second or faster). Checking the debug log,
 I see lines like this:

 {{{
 (23:17:53) oscar: Sending IM, charset=0x0000, charsubset=0x0000, length=1
 (23:17:53) sound: Playing E:\Shared Settings\Sounds\GaimSounds\message-
 outbound.wav
 (23:17:53) oscar: Sent message to TestSN.
 (23:17:54) oscar: Sending IM, charset=0x0000, charsubset=0x0000, length=1
 (23:17:55) oscar: Sent message to TestSN.

 (23:17:59) oscar: Sending IM, charset=0x0000, charsubset=0x0000, length=1

 (23:17:59) oscar: Sent message to TestSN.
 (23:17:59) oscar: Sent message to TestSN.
 }}}

 As you can see, the "Sending IM" is not always followed by the "playing
 sound" line. Same thing happens for message received--Pidgin won't play
 the sound every time if multiple events occur quickly. I am using custom
 "sent message" sounds but the same problem occurs for the default sounds.
 This was working in Gaim 2.0 beta 6, but I think it's been broken since
 Pidgin 2.1.

 I'm using Pidgin 2.2.1 on Windows. The problem happens on the AIM
 protocol, not sure about others.
