Here's my 0.02 Euro (feel free to correct errors).

/tmp in RAM surely refers to Solaris. On Solaris, /tmp is actually
implemented as pages taken from RAM+swap - this is no problem since it is
supposed to be erased on reboot. Unless Solaris is very stupid, there is
actually no duplication between the filesystem and the cache, since the
filesystem is actually in the cache!

/var/tmp is a normal disk-based filesystem.
