If the Heap size exceeds a certain limit, garbage collect till you are below it again

How creating nested hash tables explicitly/imperitively was much simpler than LINQ expressions

	// This is the code that replaced all the code below this function:
	protected override IDictionary<int, Dictionary<string, string>> GroupAndFlatten(IEnumerable<PassengerImport> imports) {
	var paxImports = imports.GroupBy(x => x.PassengerId);
	var paxes = new Dictionary<int,Dictionary<string,string>>();
	foreach(var row in imports){
	var paxid = row.PassengerId;
	if (!paxes.ContainsKey(paxid)) paxes[paxid] = new Dictionary<string,string>();
	var paxHash = paxes[paxid];
	if(paxHash.ContainsKey(row.Key)) paxHash[row.Key] += " "+ row.Value;
	else paxHash[row.Key] = row.Value;

JSPacakger

	// Only want one JSPackager in existance, so lets only create
	// one if we need to
	if (typeof(JSPackager) == "undefined") window.JSPackager = {
	// the head tag of the document
	_head : document.getElementsByTagName('head')[0],
	// a script tag to clone
	_script : (function(){
	var s = document.createElement('script');
	s.setAttribute('type','text/javascript');
	// defer doesnt seem to work with this scheme and so we defer manually in removeLoadedDeps
