I guess what Jamie meant is that during delay-time ramps, the signal in the 
buffer is being played at a  speed!=1 which produces a temporary pitch 
shift.

If what you want is to change the delay time every once in a while, I once 
implemented it by using 2 delay lines and switching among them: while delay 
line A is being used, you change the delay time of delay line B and then, 
once the critical zone is passed away, cross-fade to delay line B and leave 
delay line A idle.... and then viceversa again and again ..... something 
like that. I also used feedback.

If you need to _continuously_ change the delay time without shifting pitch, 
I guess you need to apply the same techniques that are used for 
"non-transposing" time-stretching....
