It is also bad to restrict the build to (say) a single CPU just because the corresponding rcutorture run uses only a single CPU. This commit therefore adds a kvm-test-1-rcu.sh ability to pause after the build completes, which will allow kvm.sh to do a number of builds serially (with each build thus having the full system at its disposal), then allow the rcutorture runs to proceed in parallel.
