What happened to the case where we just fill memory full of dirty file
pages backed by a remote disk?

Processes which are dirtying those pages throttle at
/proc/sys/vm/dirty_ratio% of memory dirty.  So it is not possible to "fill"
memory with dirty pages.  If the amount of physical memory which is dirty
exceeds 40%: bug.

Hi Andrew,

So we make 400 MB of a 1 GB system unavailable for write caching just to
get around the network receive starvation issue?

What happens if some in kernel user grabs 68% of kernel memory to do some
very important thing, does this starvation avoidance scheme still work?

Daniel
