For my education -- which methods are responsible for those conversion of user-entered

This sounds complicated. Is there no way, in the code that handles user-entered text in
console to:

1. Figure which console view has generated that text
2. Figure, from that, which main window is that
3. When GDB response, change debugging context only in the window found in (2)

OK. I've posted a description of how threads should work in MI to the gdb mailing list,
eariler today.
