I was just pointing out that freeBSD is different than linux nd for one thing
it is good because if there is a bug in freeSD VM, it won't run rampant
because you can explicitly limit kernel cache and other parameter.
OTOH, freeBSD VM anyways works. And running unlimited kernel cache allowed
linux to iron out some of corner cases bugs.
Not a concern anymore I believe but having choice is always great..
