+//
+// If the calling thread goes away, any function which accesses the calling stack 
+// will blow up.
+//
+//  example:
+//
+//     myFoo->bar(&x)
+//
+//     ... thread goes away ...
+//
+//    bar(PRInt32 *x)
+//    {

+//
+//   
+//  So what gets saved?  
+//
+//  You can safely pass base types by value.  You can also pass interface pointers.
+//  I will make sure that the interface pointers are addrefed while they are being 
+//  proxied.  You can also pass string and wstring.  These I will copy and free.
+//
+//  I do **NOT** copy arrays or strings with size.  If you are using these either
+//  change your interface, or contact me about this feature request.
