  Because:
1) this ticket is still open in Trac
2) this issue is still present in pulseaudio-0.9.21-2.fc12.i686
3) I've added link, so people searching about this problem could 
   found ticket

  I don't see what saving/restoring has to do with restoring. For me,
it is about temporary raising global volume without rescaling samples
already in buffer. So, when I have Totem playing at -10dB and it fills
the buffer. Suddenly, event sound with volume -7dB comes. For the
duration of event global volume is bumped to -7dB and buffer filled
by Totem is played two times louder than intended.
  I stumble into it almost every day — I have event sound enabled
and set significantly louder than music and movie streams volume.
Everytime I click a button having something played in background,
I get temporary loudness bump.
