Just my 2 cents, but I did a bit of testing here on 279 running on
Wine / Ubuntu, and I'm on my lan which is like downloading and
uploading to myself at the same time, but...
I notice my memory usage according to HFS goes up by an unbelievable
amount and stays after the test is finished. My system monitor doesn't
show that, nor does the swap file. Only thing it shows is CPU usage goes up,
then drops back.
What is interesting, is when I exit the folder I downloaded from, memory
displayed by HFS drops back to normal?
