Doing a little web research, you will notice those todo-lists with "cleaner" being the top item for...years! 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. :( Jörn -- You ain't got no problem, Jules. I'm on the motherfucker.
