On my system, it's surely not guaranteed. But it's perfectly adequate
for building soft real time systems.
My point is that the task switching overhead itself is very low on
Linux. I did not say anything about the granularity of the time slice.
My test program also includes the overhead in accessing a shared
protected object, btw.
