Right, you only need swap to be able to flush dirty pages. Clean
code (and even clean data) pages are simply dropped and reloaded from
the disk image later on if needed again. With careful program
management you can run without swap.
Also, do performance testing with dynamic-linked verses static-linked
binaries. Static-linked binaries may look larger, but they have a
much lower dirty-page overhead then the dynamically linked equivalent.
It depends on the situation but it is definitely worth testing.
