In jquery 1.3.2 is no problem but 1.4.2 event still trigger.

Okay, I did find the documentation here:
"If there are multiple handlers registered, they will always execute in the order in which they were bound."
So the remaining issue is with unbinding handlers inside a handler itself.

And... calling e.stopImmediatePropagation() takes care of that.

Why this behavior doesn't equal 1.3.2? So many plug-in doesn't work.
Note that the "bug" alert appears only once.
I think there may be assumptions here that are not part of jQuery's documented behavior as far as I know:
Event handlers on an element are not guaranteed to be executed in the order they are attached.
Unbinding event handlers *inside* a handler for that event may not prevent a handler from being executed during that event's delivery.
