IntervalMs = application:get_env(?APPLICATION, furtle_interval_ms, 10).

Because you never know when you'll need to change the furtling
interval in production.

But, if you're needing to slow things down to allow distributed tests
to work, you've got a race condition, and sleeps (effectively) are a
band-aid. You should be waiting for (whatever) to finish before moving
on. We do this, mostly, by repeated polling and, occasionally, by
waiting for events.

Unless you're deliberately inducing race conditions and _that's_ why
you need the slowness, of course...
