[gentoo-dev] avoiding urgent stabilizations

From time to time there are stabilization bugs where the current stable
is broken. For example, https://bugs.gentoo.org/show_bug.cgi?id=353487

However, in theory that should not happen, because presumably the
current stable has been tested in the past and considered not broken.

Of course that would be rather idealistic to assume such situation will
never happen, but can we do something more to avoid detecting important
problems in the stable tree too late? Are we missing something when
stabilizing some important packages that later causes the breakages and
need for urgent stabilizations?
