[wp-hackers] how to do a single-instance widget with the new API

[Otto]

Firstly, yeah, that's the wrong way to do AJAX. Like he said.

Secondly, single instance widgets are the tool of the devil. Don't do
it. Make it work multiply.

Third: If you're inheriting from WP_Widget, then you have a $number.
That $number is something you'll find useful for looking in that
array.
