That's a good question.  I don't know, really: what I do know is that
I don't want to be fielding many bug reports about this.

I agree.  However, I think we should be fairly careful about the

before 4.1 branches, we'll have the branch stabilization period to get
the changes pushed through to gdb and binutils.
