The current name for this is "tmpfs". Yes, on systems with low memory and low swap. On all other systems I use tmpfs for more than a year for now. The problem is that clients like xpdf open by default all PDFs in /tmp and not /var/tmp (which is still mapped to disk in all my configurations) and with lots PDFs open, the box starts swapping pretty quickly with only 4GB RAM and ZFS. Even with 8 GB RAM its a kind of problematic, when we deal with larger temporary files taken from simulations, opened by vi or other editors and stored temporarily in /tmp.
