While I don't want to discourage you, this is about the point in

Getting that one to work robustly is _very_ hard work and just today
I've noticed that mine was not as robust as I would have liked to think.
Also, you may note that by updating to newer kernels, the VM writeout
policies can change and impact your cleaner. To an extent even that you
had a rock-solid filesystem with 2.6.18 and thing crumble between your
fingers in 2.6.19 or later.
If the latter happens, most likely the VM is not to blame, it just
proved that your cleaner is still getting some corner-cases wrong and
needs more work. There goes another week of debugging. :(
