Description
The empty() method on a selectbox is _much_ slower then selectbox.options.length = 0; Maybe it is nice to check if the element is a selectbox, and then use the options.length way to empty the selectbox.

We still need to clean off the data attributes. I can't get the test case to work though.

The differences don't seem that large to me; I even increased the number of options. For cases where someone is updating large numbers selects at a high frequency and is willing to risk the memory leaks, they can set options.length=0.

I tested whats faster; the build-in jQuery technick of a while loop and your suggestion of
length=0Aldo your suggestion is faster then the while loop, it's not the while loop that slows it down; it's the expando management that is the 'problem'.
