I ran 26-rc5-mm3 with 5 split/unevictable lru patches that you posted on
19june.  I replaced patch 5 of that series with the subject patch
[rework v3, merged SHMEM fix].  This kernel ran my 'usex' stress load
overnight for 23+ hours on both ia64 and x86_64 platforms with no
problems.  I evidently did not hit the problem you did.

I'm rebuilding with a patch to a small problem that I discovered along
with your recent patch to "prevent incorrect oom...".  I'll let you know
how that goes as well.

I'll send along two additional patches shortly.
