Profanws afou oi 2.4.10 kai panw (tou linus) xrhsimopoioun thn idia vm (tou

(arcangeli) se kana duo phrunes...
Den mporw na exw texnikh apopsh alla quoting Matt Dillon[0]:
" I will admit to wanting to take a clue-bat to some of the people arguing 
against Rik's VM work who simply do not understand the difference between 
optimizing a few nanoseconds out of a routine that is rarely called verses 
spending a few extra cpu cycles to choose the best pages to recycle in 
order to avoid disk I/O that would cost tens of millions of cpu cycles 
later on. It is an attitude I had when I was maybe 16 years old... that 
every clock cycle matters no matter how its spent. Bull! "
