   They both have advantages and disadvantages.  But, the DDB is nice
   for getting the stack trace upon panic,

(gdb) break panic
(gdb) continue
...
(gdb) bt

   etc, looking a structure contents during a panic condition ...

(gdb) print *u0
(gdb) print *user
(gdb) print *proc
(gdb) set $proc = (struct user *) proc->next->next (or whatever)
(gdb) print *$proc

   etc.  (That's what I use it for :-) You also don't have to `attach'
   it.

Ok, you get me on this one ;-)
