You just need to set maximum values to barrier/limits and VM will be essentially uinlimited. Check /proc/user_beancounters to see how host VM is limited with "unlimited" values (i.e. highest possible limit value).
3 notes: 1. max limit is different on x32 and x64 machines 2. both barrier and limit must be set to these values. 3. in such a configuration if a global memory shortage happens out-of-memory killer kills some app as in native Linux system.
