I guess that we can add a dummy program to make wait for a signal in the test06.

Does something like this work?

numactl --length=1M --file /dev/shm/numa_shm --interleave=all --touch support_numa 3 &

I would be probably in favor of dropping the test07, since that does
more or less the same as test03.

Just set large enough memhog repeat parameter with -r so that it does
not finish prematurely. Or even better we can just add a few lines of
code to the numa helper so that it can memset the memory in a loop just
like the memhog does.
