The odd half second here or there. A simple example is handling a page
fault or an I/O when you are doing a memory allocation. Your RT task can then
get stuck at the back of a queue of pending I/O operations.
We don't try to be 'seriously realtime' in paticular we don't deal with
priority inversion and kernel pre-emption. If it hurts when you miss
deadlines look at RtLinux
