I just sat there for a minute and stared at top. I see that everythime
Gmail goes and 'gets' new info (every half-minute or so), firefox
jumps up to 70% CPU. Also, doing nothing, X sometimes jumps to 50%
CPU. I don't know if this is normal, but I did notice it.
I'm now maning and googleing the other processes I see in top.
Interesting to know what really is going on in there.
