:I do have one question -- for the app we care about (vmware) the pages
:in the mmaped file will apparently be wired. Is there any reason why
:we couldn't just skip wired pages in vm_object_page_clean()? It seems
:like there's no point in cleaning a wired page because you won't be
:able to free it anyway, so it doesn't matter if it is dirty...

:Thanks,

As far as I know vmware is not wiring pages down.
vm_object_page_clean() is called from higher levels to clean a specific
range of pages in an object. For example, I believe it is called
from msync(). We obviously do not want to prevent it from cleaning
wired pages!
