Hmm, this approach is racy if there are other users

I mean that this works only when the entire safe/set/restore
operation is nested or sequential.

Good point!

However, I tend to think that we don't need to care about it
that much. Having a counter to permit nesting would probably be
better, but, like you said, it's unlikely that we will see any
problems with ignore_console_lock_warning anyway. So we can keep
it simple [IOW - the way it is].
