I agree very much.

Vishnu, please think about those (me in particular ;) who need to backport
the fixes from time to time. Just suppose we have a bug in, say,
do_notify_parent_cldstop(), and it is fixed later. Now I will likely need
to backport your change too, and this is not trivial in general, plus this
adds the additional risk.

Oleg.
