Re: New patch for Linux

["Yair Wiseman" <wiseman@macs.biu.ac.il>]

Dear Rik van Riel,

Thanks for your comments. You indeed have a point. We used 128MB of RAM which is VERY small, so one second would be
enough; therefore I agree that your remark about the small quantum is correct - a common nowadays RAM is larger and
the quantum should be longer.

The first author of the paper was an MSc student of me and the code was at his home-page, but when he left the
university his directory was removed. We tried to find his code and we found just the code of 2.4.20. I put it at:
http://u.cs.biu.ac.il/~wiseman/moses.html

Thanks for considering our patch,

-Yair.
