Subject: 2.6.28, limiting cpu time doesn't work

Hello,

after upgrade to 2.6.28 ulimit -t doesn't work. for example:

bash# ulimit -t 3; cpuhog

(where cpuhog is any program that continuously use cpu)
with 2.6.27.20 cpuhog gets killed after 3sec as expected.
with 2.6.28, 2.6.28.8, 2.6.29-rc8-git4 it's keep running indefinitely.
ulimit -a and /proc/<pid>/limits show that cputime limit was set correctly.

have i missed some global api changes? recompilation of recent glibc with new kernel headers and shell doesn't help...

ps please cc me, i'm not on the list
