The minimal-net target, as currently written, wakes up the CPU every millisecond to check for packets, and will only react in real-time to input from stdin. If you are running this on a laptop battery, your battery will quickly drain. This change allows the CPU to idle when there is literally nothing to do while still being responsive to input from stein and/or incoming packets. This fix should significantly improve performance while significantly improving power usage. Win-win. Also added `_xassert()` implementation so that the contiki- provided `assert()` macro will work properly when used on this platform.
