Right, I forgot about the pokels. But I missed the rationale behind flushing _all_ the pages with ref. count zero. I understand why it has to be zero, I just do not understand why you have to flush all instead of just a few.
Perhaps I just read over the text, can you please point me to it?
I meant this (about peeking all pages because of the Mach bug):
"It's true that with large disk cache, e.g. 512M, this potentially will re-read the whole cache from disk. But if we reach this point, the microkernel is telling us that all is already read :-)"
Obviously this is not directly related to your questions (why not flush just some pages, not all), so there is no "rationale" behind this case.
Now I agree that flushing just some pages is always better idea.
