What would that be, exactly?

There is RTAI/LXRT and RTL, both of which provide various forms of 
kernel and user space hard real time scheduling. Provided you have 
compatible drivers (which is no issue when dealing with turn-key 
systems), you can basically just use one of those instead of 
Linux/lowlatency to cut worst case latency down to the µs range. The 
only practical limits are RAM access times (cache misses add to the 
scheduling latency) and raw processing power.
