Sorry about the delay, the upgrade took longer than expected and the
initial kernel didn't actually solve the load issue completely.  I've
since installed a very slightly modified build of the initial kernel and
had to reboot hera twice more (both to the same kernel, but I again ran
`lsof -p <pid>` and had Linux panic on me.  A feature that has very
consistently bitten me on a number of kernels and a number of systems
lately).

This second kernel is at least, so far, acting a lot closer to what I'd
expect from hera, but the disk cache is still filling.  I'm going to
keep an eye on it for a bit longer tonight.  As a note, the only
difference between the first 3.1-rc1 kernel and the second, that is
currently running, was the explicit disabling of IMA and recompiling the
kernel.

I'm going to give the all clear at this point, I won't be doing any more
reboots without an additional e-mail and notice.  If you see any
problems or issue, or you catch that the loads are spiking up into the
stratosphere, please let me know.
