Why?
The problem of startup/shutdown cost and how many cores you have are
completely orthogonal.
I see no problem in starting N threads at the initialization time, use
them throughout the application lifetime and then shut down at the end
(or never).
The cost of these operations is irrelevant. Make it 10x what it is and
I will be still fine.
If your favorite programming model involves lots of short-running
threads that have to be created and torn down repeatedly, then it has
no relation to multicore. It is just a bad resource usage pattern.
