>From the HP-UX 10 release notes:

#begin
* The nice() system call influences how aggressively the pager will
steal pages from a process. The "more nice" the process is, the more
likely it is that the pager will steal its pages. The HP-UX 9.0 pager
treats all processes equally, and the nice() command is used to modify
process priority in relation to CPU usage. In 10.x, process priority
can also affect how much of the process stays in memory, thereby
improving system response time for processes that are not "niced." For
more information on nice, refer to the nice(1) manpage.
#end

Does Linux do something similar? If not, is it worth considering?
