[Greasemonkey] setTimeout() problems

[Jonathan Buchanan]

setTimeout needs a function to execute - you're immediately calling
the function you just defined, so as you're not returning anything in
that function, you're really passing undefined to setTimeout.

Try returning a function which forms a closure over the argument.

function(arg) { return function() { alert(arg); }; }(foo);
