Re: Nothing new in "Real Time" Unix...
Its been a kernel build option for some time. Its been a few years since I had to build/port a Linux for some hardware that included the RT option but it was just one of several scheduling algorithms you could choose from.
For a lightly loaded system --- which *should* be the typical user (If it wasn't for all the damn popups and other crap that materializes in a typical web browser these days) -- you won't notice the difference between it and the regular scheduling algorithm. The goal for this particular build was supporting CAN, a type of networking that sits awkwardly on Linux at the best of times.
