Such nodeLists are kind of arrays, but immutable. I don't know what
jQuery does to an array like element passed to $(). If its trying to
alter the passed in array that won't work...
To verify this one could try:
var elems = [];
for (var i = 0; i < theForm.elements.length; i++)
elems.push(theForm.elements[i]);
alert( $(elems) );
