Answer 1

If you are using Thread.sleep(), just have the static method change a static global variable to something that you can use to indicate blocking the method call?

public static boolean abcRunning;
public static void abc()
{
    if (YourClass.abcRunning == null || !YourClass.abcRunning)
    {
        YourClass.abcRunning = true;
        Thread.Sleep(60000);
        // TODO Your Stuff
        YourClass.abcRunning = false;
    }
}

Is there any reason this wouldn't work?
