gdb with many windows: kill associated buffers doesn't always work

[Klaus Zeitler]

1. emacs -Q&
2. eval (setq gdb-many-windows t)
3. M-x gdb

Now when I finish my debug session, the associated buffers don't get killed
automatically.
When I restart gdb without killing those associated buffers, I see the same
behavior. But when I kill all associated buffers and then restart gdb, the
newly created associated buffers will be automatically killed when I finish
my gdb session.
