Calls (including the body of the called function) have zero latency. The FMA drops after the call returns.

The Mill spiller not only saves the furrent belt and scratchpad, but also everything that is in-flight. The in-flights are replayed when control returns to the caller, timed and belted as if the call hadn’t haoppened.

That how we can have traps and interrupts be just involuntary calls. The trapped/interrupted code is none the wiser.
