Re: Add pacct_struct to fix some pacct bugs.

Hi, I noticed three problems in pacct facility.

1. Pacct facility has a possibility to write incorrect ac_flag
   in multi-threading cases.
2. There is a possibility to be waken up OOM Killer from
   pacct facility. It will cause system stall.
3. If several threads are killed at same time, There is
   a possibility not to pick up a part of those accountings.

The attached patch will resolve those matters.
Any comments please. Thanks,

Thanks, but you have three quite distinct bugs here, and three quite
distinct descriptions and, I think, three quite distinct fixes.

Would it be possible for you to prepare three patches?

It may be possible. Please wait for a while to separate it into
three-part and to confirm its correct behavior.

Thanks,
