Processes exist in separate virtual memory spaces. Threads in the same process exist in the same virtual memory space. This is a fundamental principle of virtual memory. Mixing this up with a filesystem or any shared resource is completely nonsensical. Naive oversimplifications like this indicate a lack of understanding of how and why computers are architected as they are in the first place. Virtualization could be said to be an extrapolation of virtual memory and in fact does offer sub virtual memory, but to equate threads, processes, virtualization and shared resources as the same thing is grasping for simplicity that isn't there by making comparisons that aren't true.
