Recently I read a clever solution to this problem: dampen the spring with a 
dab of silicon rubber adhesive.  A small blob of this stuff evidently intro-
duces enough mechanical damping into the spring so that it is impossible
for a high frequency squeal to develop.  Haven't tried it but it sounds good.
