hardware_disable_test produces 512 snippets like
...
main: [511] waiting semaphore
run_test: [511] start vcpus
run_test: [511] all threads launched
main: [511] waiting 368us
main: [511] killing child
and this doesn't have much value, let's just drop these fprintf().
Restoring them for debugging purposes shouldn't be too hard.
