You're still ignoring that a disk based filesystem puts up the same memory pressure, even more so for the journal and metadata overhead. As I pointed out the tipping point can be easily recreated by writing to NFS. A slow USB device works too if you have one big enough. I haven't seen the same behaviour with tmpfs but then again I don't put files much much larger than my ram in /tmp.
