Its not for perfomance, but for stress test. Leave it running in the
loop for a week and keep using your pc as usuall. If nothing crashes,
I would be pretty confident in a such setup. And even if someone
experienced enough would give "yes" answer to you, no one gaurantees
you that next kernel update will not break it.
P.S. Nothing is sure but death and taxes :)
