tmpfs is not a block device. It's a filesystem that takes its storage 
blocks from VM subsystem (so they reside either in RAM or in swap - it's 
the task of VM to decide that) and builds a filesystem out of these.

When you mount several instances of tmpfs, each instance has its own 
blocks and own namespace. So files with the same name in different tmpfs 
mounts are not a problem - they are just different files.

When you really want to use the same tmpfs instance in multiple mount 
points, you could probably use "mount tree symlinks" - lofs in Solaris, 
bind mounts in Linux etc.
