[PlanetCCRMA] too many processes?

I might add that linux uses memory differently than other operating
systems.  It's not unusual at all for me to find 50% of my 640 meg "used
up" when my laptop is "sitting still".  In linux the phrase "unused
memory is wasted memory" is quite accurate.  The important part is how
much swap is being used IMHO (writes to swap take a lot of time and hog
interrupts).  Don't worry about memory usage unless it's a single app
that's hogging everything (you can find if that's the case by running
top) for the most part linux uses memory very efficiently.
