    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.
