If it doesn't change much, that's fine. Regarding the 'bt -O' change... If I run 'crash' in root's $HOME a '.crashrc' will get executed twice. I cannot put 'bt -O' in a .crashrc file and get predictable behavior. It'd be good to have a mechanism which is idempotent. I've attached patches which change 'bt -O' to accept an optional 0/1 argument to fix the value.
