I know you've given me advice before and I did try gdb-mi again, but it
I fint it is still unusable.  I can think of two reasons:

1. I am limited to using 80column frames and the windows that gdb-mi are
too small and their content cannot be viewed without too navigating
through too many keystrokes - repeated at every `step'

2. I prefer to use display-buffer-reuse-window when possible for
display-buffer.  When stepping through functions which are spread out in
different files I need to have all the files open at specific points
(i'm trying to understand the code).  Every `step' alters the window
configuration that I expect and I spend more time in getting back to
where I was before invoking the gdb action, than actually debugging.

On the other hand gud-gdb is more managable.  With annotations it also
pops to the buffer with the annotated source line (when available) but
the overall disruption is much less.
