I did more testing. It does not happen right after boot.

It is not 100% reproducible, I *think* I need to fill pagecache
with filesystem cache first
(grep -rF qjklwmhflakwghfjklah $source_tree does this nicely)
and let the box sit idle for a minute or two.

Then I run oom_trigger. Typically it eats ~350mb and is killed.
That is, when things are working normally.

But sometimes it eats only ~250mb, and top before/after that looks
like this:

before oom:
top - 08:14:12 up 15 min, 1 user, load average: 0.37, 0.14, 0.06
Tasks: 78 total, 1 running, 77 sleeping, 0 stopped, 0 zombie
Cpu(s): 0.4% us, 1.1% sy, 0.0% ni, 94.2% id, 4.2% wa, 0.1% hi, 0.0% si
Mem: 112376k total, 108564k used, 3812k free, 14968k buffers
Swap: 262136k total, 2592k used, 259544k free, 80516k cached

after oom:
top - 08:14:27 up 15 min, 1 user, load average: 0.52, 0.18, 0.07
Tasks: 78 total, 1 running, 77 sleeping, 0 stopped, 0 zombie
Cpu(s): 0.4% us, 1.3% sy, 0.0% ni, 93.4% id, 4.8% wa, 0.1% hi, 0.0% si
Mem: 112376k total, 107704k used, 4672k free, 10336k buffers
Swap: 262136k total, 84168k used, 177968k free, 4056k cached

Both mem and swap 'used' values look strange.

Complete top outputs are attached.

Subsequently I automated the thing, and another such
event was captured (tarball of /proc/N/status before
and after OOM is attached):

#!/bin/sh
cd status_before
echo "PID.... Before......................... After......................"
for b in *; do
a=../status_after/$b
echo "$b:"$'\t'`grep VmSize $b`$'\t'`grep VmRSS $b`$'\t'`grep VmSize $a`$'\t'`grep VmRSS $a`
done

PID.... Before......................... After......................
