Its the only way, that I know of, to protect the contents of a window. I think
I only make the windows dedicated *after* I put the gdb-related stuff in
them. I take your point that dedicated windows can be a nuisance. Thats why I
try to undedicate any source buffers left after a debug session. The
special-frames-regexp seems to make the window dedicated indirectly and so, to
be honest, I can't see how this differs, in practice, from what I had before.

I've changed these (apart from gdb-frame-gdb-buffer because the gud buffer
is covered by same-window-regexps). I've removed the menubar and minibuffer
from the resulting frames using special-display-frame-alist (maybe this
make no difference with your setup). I tried not to select the buffer by
using display-buffer instead of pop-to-buffer but it still seems to select
it anyway (Is this a bug in Emacs?).
