         * Runs the garbage collector.
         * 
         * Calling this method suggests that the Java
         * virtual machine expend effort toward recycling
         * unused objects in order to make the memory they
         * currently occupy available for quick reuse. When
         * control returns from the method call, the virtual
         * machine has made its best effort to recycle all
         * discarded objects.
         * 
         * The name gc stands for "garbage collector". The
         * virtual machine performs this recycling process
         * automatically as needed, in a separate thread,
         * even if the gc method is not invoked explicitly.
         * 
         * The method System.gc() is the conventional and
         * convenient means of invoking this method.
