[PlanetCCRMA] Denormals info required

[nigel henry]

Thanks for the PDF Fernando. I didn't look at it last night, it seemed a bit 
heavy, and it was late. I ran Soundtracker on FC2 all night with no problems. 
It was working ok the next morning. Read the denormals PDF. Still quite 
heavy, but I see what it's getting at. I was going to ask if there was a way 
of interrupting the CPU when it was being hogged by denornals, apart from 
rebooting, so as to be able to close a rogue app, but I think I'm going into 
the realms of science fiction. Thanks for all your help and advice. Nigel.
