There are plenty of things that wake the system more often than this script. And again, this is a stop-gap measure, not a solution. I find this much more power friendly than reaching into my pocket to find my battery 100% drained because of a kernel bug...

I would love to be able to tune the watchdog to look for this. And I'm sure writing it as a native app in C would lower it's processing time further. If I could, I would have it hook into the frequency scaler to only bother checking when the CPU is running at top speed. But I don't know how to do that from a shell script. Is there a dbus message I can hook against to only wake when this is happening? I'm very open to changes.
