> When deciding what memory to make available to tasks (if not explicitly configured), mesos agents currently reserve 1GB or 1/2 of system memory. 
> I'd really like to be able to configure the reservation amount so that I don't have to reproduce the system memory lookup and math in order to configure "mem=(system memory - reservation)".
> Ideally this would be configurable with a command line argument and environment variable like "--reserved-memory=512".
