Solaris (2 if you will) does indeed swap processes in case normal paging is
deemed insufficient.

Many programs allocate memory they never use. Linux allows

This is the case with most OSes now. Swap out stuff early, perhaps
keep it in RAM and swap at the same time, and the kernel can choose
what to do later. In Linux you can set it in

I know that according to the documentation Solaris is supposed to be

Agreed, however:
#1 Shorter values of forever (like, say, daily) may still be useful.
#2 This relies on knowing in advance what these processes
