This can happen if a task runs for too long inside the kernel

cpu. The fact that RCU grace period eventually happens
and the dentries are freed means that something intermittently
holds up RCU. Is this 2.6.10 vanilla or does it have other
patches in there ?

The 2.6.10 was modified. All the results with the dcache debugging patch applied were from vanilla 2.6.14-rc2.

It's perfectly repeatable as well...every single time I run "rename14" the OOM killer kicks in.
