Ohh you talk about call pipelines, I totally missed the point. You are talking about time-constrained systems where an answer in the timeframe is required, right? Otherwise the timeout does not make sense, or would you do such precise timeouts even in non-time-constrained systems?

Anyway, seems to make sense to plan for this timing-wise. Allows addressing and seeing performance bottlenecks. Thank you for spelling it out for me!
