Hmm. You may be correct, but I'm pretty sure that doesn't account for *that*
much CPU. I've had smaller apps running and they don't consume much CPU.
I think that the high CPU consumtion can be attributed to the dreaded
garbage collector doing it's thing once every second or so...
I guess the Sun JDK doesn't use a very efficient algorithm (they're hard to
write, I know). If you launch a large baby like Netbeans Developer you'll see
the same effect.
