This sounds likely, as the requests are processed
serially.

It is not so common to remove behaviours, but to toggle
their "enabled" property. So maybe you can do something
like this
add(imageDiv.add(new AjaxEventBehavior("onmouseover")
{
private boolean called;
@Override
protected void onEvent(AjaxRequestTarget target)
{
div.setVisible(true);
imageDiv.remove(this);
target.addComponent(div);
target.addComponent(imageDiv);
called = true;
}
@Override
protected boolean isEnabled()
{
return !called;
}
}));
or if it doesn't do the trick, just do the check in onEvent().
Best wishes,
Timo
