thanks for the diagnosis

[Canada <canada@voyageronline.net>]

thanks to all who advised me that it's probably the throwout bearing or 
pilot bushing making the high-pitched whine when i depress the clutch.  
one followup question:  some of you said it probably doesn't have to be 
replaced immediately.  short of letting it fail completely, is there any 
way to tell when driving it anymore is too risky?
