I can't follow that thought. As long as there's a way of telling lwIP how much
time has passed (this could even work by comparing return values of
sys_now()), it doesn't matter if you idle-loop or really sleep.

Of course. The question is whether that's a problem or not. The only problem I
see is the DHCP lease time, the rest of the timers shouldn't care for (rather
small) drift.
