Not sure the performance and memory consumption is that great (don't have any numbers) given that the whole point of having a libprocess actor is its low overhead, so would prefer maintaining conformance over performance :). But if you feel strongly about this, don't have have a strong argument against it either, so go ahead and drop the comment in that case.

Since it doesn't need an actor, it seemed better to avoid the memory, performance and compilation time costs. If it does need one later that's preetty easy to change.

Any reason why we are not inhertiting it from a `MesosIsolatorProcess` ? I see that given its current implementation it doesn't need to be an actor. But might make sense to follow the idiom set by other isolators to keep it Future proof?
