Or fast systems slowing because an animated screensaver is being run? 
This can easily happen if you ask someone else to run Prime95 on 
their system as a favour.

I remember getting "wound up" about this shortly after I joined the 
project. George replied that these problems have a way of sorting 
themselves out; experience proves him right.

Well _I_ don't!

Now I believe Henk is a responsible individual, and I've no reason to 
suspect Jeff is any less so. The system we have at the moment is 
reasonably robust and will stand a certain amount of abuse. However, 
abuse on a large scale will break it. I don't want to be responsible 
for that. What I mailed to Henk privately amounts to a minor form of 
abuse of the system. One paragraph of that private message reads:

(start quote)
Obviously you should be careful when doing this, else you are likely 
to be accused of "pirating" assignments. Also there would be chaos if 
several people were doing this, which is why this reply is being sent 
to you only and not to the list.
(end quote)

Jeff, if you (or anyone else, for that matter) want to take advantage 
of the idea I mailed to Henk, I suggest you mail Henk privately and 
discuss amongst yourselves how you're going to coordinate your 
combined effort. My contribution to your "sturmgruppe" ends here 
because I don't believe that anyone's CPU cycles are inherently more 
valuable than anyone else's.

Oh, and if you happen to find a new Mersenne prime whilst you're 
working in this mode, I would hope that you'd be prepared to share 
the credit with any other person who happens to "own" the PrimeNet 
assignment at the time.
