>  and attaching DebugView to GDB

DebugView is not attached to a specific application, it is simply
acquiring a global windows resource that exists system-wide and only
once and can be held by only one application at a time. It will then
receive messages from windows and read the text from a shared memory
block that it holds exclusively during the whole time it is running
and that exists only once. A DebugView-like application will receive
*all* messages from all running applications on the system.
