OK, I did that. I am bit unhappy that I had to do it, though. The patch 
dates back to January (!) and Ubuntu folks have been carrying it for a 
while now.

Looking at the amount of reports out in the wild (on Ubuntu forums, 
etc.), I really don't understand why this wasn't submitted earlier. 
Instead, the bug was flagged with low priority because it's "just a 
performance problem." Considering the system is more or less unusable 
for me, I obviously think it's a critical bug fix.

Yes, agreed completely. We probably want ACK from Jesse and Bjorn, though.
