The documentation for STARTUPINFO says this about STARTF_USESTDHANDLES:

   If this flag is specified when calling one of the process creation
   functions, the handles must be inheritable and the function's
   bInheritHandles parameter must be set to TRUE.

So, as I said, if you redirect the streams then you inherit all 
inheritable handles.
