var exists = false;
$('#select-box option'...
ThreadStatic v.s. ThreadLocal: is generic better than attribute?
...thread. For example, say you have this:
[ThreadStatic]
private static int Foo = 42;
The first thread that uses this will see Foo initialized to 42. But subsequent threads will not. The initializer works for the first thread only. So you end up having to write code to check if it's initialized.
