Yes, I think people understood what I meant. By "long deadline" I meant
the time needed for an event to happen or critical section to finish is
so large that it should be easy for the event to occur or a critical
section to finish within that time range.

In a rate monotonic scenario, I usually consider 3 time ranges. Period,
deadline and runtime. Where, period >= deadline >= runtime. Usually
runtime is deadline - (enough for some delta). Thus, when I say
deadline, that is just a shorter version of "time it takes where a
deadline must be reached".
