The author of the tmpfs kernel code mounts his /tmp as a tmpfs 
filesystem, so everything goes into RAM until it runs out, then the old 
stuff goes into swap. The only catch is that you can't mount loopback 
filesystems on tmpfs. This won't affect any gentoo system scripts, but 
means that you can't (say) build a boot floppy on /tmp (you could use ~ 
or /var/tmp). 

However, I think one of the previous posters was right in saying that 
/var/{run,lock} would be more trouble than it was worth - they would be 
taken care of amply by the kernel buffer cache.
