Hmm... Until today I thought that it is a good administration style to create a several gigabyte swap partition (which is normally almost unused, but just for the case that some program needs much virtual memory), and use tmpfs for /tmp. I thought that it is good for two reasons - disk space is not wasted for /tmp (and /tmp still has several gigabytes of space), and short-living temporary files such as gcc intermediate files normally reside in memory, which is more effective than using a filesystem on a disk.
If I understand you correctly, the above is not true at least for a desktop system with 256M of RAM?
And what about LTSP server with 2 gigabytes of RAM (and 6 gigabytes of swap) that normally runs 10-15 KDE sessions with mozilla's and openoffice's?
