Delaying would not solve the problem as it is...

If the compilation will fail at a certain point (and it will fail,
since this is a complete new thing) -- would it be possible to resume
even some tweaks, hacks and patches (even certain recompilations)
would be needed in between?

Can I stop a running emerge @world and resume later?

How does a restarted emerge @world recognizes packages, which are
already compiled according to the new standard?
