Not much point in that, IMHO - the virtual memory system will
usually swap
out inactive apps to make room when the active app needs more
physical RAM.
And if an app is in the background just waiting for user input,
it's taking
a tiny amount of CPU anyway.
In fact, telling all applications to quit forces the OS to page in
significant chunks of those apps so they can actually execute the
quit request. That causes a bunch of VM churn and will hurt
performance in the immediate term.
