Because this is something you yourself might have
been working on, at least in an overseeing mode,
so I show this post to you directly, as an FYI.

I too have noticed this fast scrolling and been annoyed by it, so I
tried Kai suggestions and found that they have no effect on the fast
scrolling.
While trying them I believe that I may have found a bug.  When I placed
the cursor at the start of a word before dragging commenced scrolling
proceeded at a reasonable rate (and with the mouse-scroll-delay set to
0.5 rather than 0.25 scrolling was noticeably slower), but when I placed
the cursor in the middle of a word scrolling took off like it is going
to a fire (regardless of the value in mouse-scroll-delay).  This occurs
in the following modes: text mode, awk mode and shell script mode.
