如何更改CPU缓存的关联性？(How do you change the associativity of the CPU cache?)

 根据设计，Actionscript是一种事件驱动语言。 它还保证代码在单个线程中执行，即如果函数调用开始，则在第一次调用完成之前不会执行其他（新调用）actionscript代码。 
 
 话虽这么说，你应该拥有的是将完整的处理程序传递给sql（...）。 
 
function sql(saveorload:String, sqlstring:String, completeHandler:Function):void
{
    var sqlloader = new URLLoader();
    var sqlrequest = new URLRequest("http://***/sql.php");
    sqlrequest.method = URLRequestMethod.POST;
    sqlloader.addEventListener(Event.COMPLETE, completeHandler);//tell urlloader to use the complete handler passed in parameters    
    var variables:URLVariables = new URLVariables();
    variables.sqlm = saveorload;
    variables.sqlq = sqlstring;
    sqlrequest.data = variables;

    sqlloader.load(sqlrequest);
}
 
 然后从其他地方使用它，例如： 
 
sql("1","SELECT * FROM songs WHERE `flag2` LIKE '0'", sqldonetrace);
function sqldonetrace(e:Event)
{
    var sqldata:String = e.target.data;
    trace (sqldata);
}
 
 另外，我认为你应该检查来自urlloader的错误事件。 将另一个参数作为errorHandler传递给sql 

Actionscript is, by design, an event driven language. It also guarantees that the code executes in a single thread i.e. if a function call starts, no other(new call) actionscript code would execute until the first call finishes.
 
That being said, what you should have is to pass a complete handler to sql(...).
 
function sql(saveorload:String, sqlstring:String, completeHandler:Function):void
{
    var sqlloader = new URLLoader();
    var sqlrequest = new URLRequest("http://***/sql.php");
    sqlrequest.method = URLRequestMethod.POST;
    sqlloader.addEventListener(Event.COMPLETE, completeHandler);//tell urlloader to use the complete handler passed in parameters    
    var variables:URLVariables = new URLVariables();
    variables.sqlm = saveorload;
    variables.sqlq = sqlstring;
    sqlrequest.data = variables;

    sqlloader.load(sqlrequest);
}
 
And then use it from some other place like:
 
sql("1","SELECT * FROM songs WHERE `flag2` LIKE '0'", sqldonetrace);
function sqldonetrace(e:Event)
{
    var sqldata:String = e.target.data;
    trace (sqldata);
}
 
Also, I think you should check for error events from urlloader. Pass another parameter to sql as errorHandler
