:However, it is now easy to notice that after having been relieved from 
:heavy loads the system appears to treat some of the remaining processes 
:as if the system's primary resources are still scarce. The result is 
:some applications remain less responsive, long after they should have 
:returned to being "snappy". I suppose this could have something to do 
:with swapping pages back into primary memory after the system load has 
:been lightened.

    If your system is paging a lot, then the data related to these processes
    would have to be paged in again.

    Running a 'vmstat 1' or a 'systat -vm 1' in an xterm while playing
    around and observing the results may allow you to characterize the 
    problem a bit better.
