The double-click behavior should be an extension of the single-click
behavior. [cf the Finder: first click selects, second click opens]
If you really want distinct behavior, you can use a modifier key
(preferred) or delay doing anything about the first click until the time
for a double-click has expired.
The same sort of argument applies to triple clicks, etc.
