It was I who contacted Balbir Singh (which subsequently commented
here), Tim Gardner notes on the mailing list:

    "Actually, I was messing with this feature independently this morning. I 
    think our initial performance impact assumptions were a bit pessimistic."

Does that mean that there never was a performance impact as initially
suggested, it was just assumed to exist. I.e. this was always a
non-issue.

I'm not looking for someone to blame, just wondering if this needs to
be followed up with upstream. And whether running a kernel with
CONFIG_TASK_DELAY_ACCT=y and without nodelayacct actually has a
performance impact that users of Ubuntu might be concerned about in
some odd cases.

Thanks.
