The goal here is to not have constant wakeups due to timeout. Do
not attempt to clean things up nicely before termination -- just
terminate instead. We can setup a proper termination system in
the future, I first want to see if this makes a difference.
Also, change xmon to use pipes for communication, so that it can
wait without timers as well.
Also, `write` directly for logging, so that we know the logs will
make it to the file after the logging call returns (since we now
do not have the chance to flush them afterwards).
The main thing that's added is full RS support, but a lot of things
were rejigged along the way. The tests are still a bit lacking,
and will be augmented in future commits.
Also, produce fully static binaries. This means that `gethostname`
does not work (doesn't work with static glibc unless you build it
with `--enable-static-nss`, which no distro builds glibc with).
