As the 2.4.19-pre mainline got your buffer throtteling changes I guess it
has the same issues?  Do you think it's worth to submit that patch to Marcelo
even that late in the release cycle?

It seems to me you ignore the comments akpm put in the split patches you
merged :)  Not only the comment to this change is superflous now, but also
I'd really like to get an answer to the remaining part of it as Andrew's
comment about that part beeing buggy makes a lot of sense to me..
