Nobody told me, even when I asked (but I was told to be patient
instead of getting an answer). This is my own conclusion after many
weeks of work. Try to install and use dbus in 8 or 16 MB RAM system
with about 300MB permanent storage. This is a small device, not a
desktop.

What is sane about having a function block, doing nothing but waiting,
sending requests back and forth with 3 daemons, and all those message
queues and forked children, when everything can stay in a simple main
loop? Even the use of glib doesn't make any sense here; glib's
interface exists to be portable even with Windows. This is something
you just can't afford on small systems. While all this makes sense in
other contexts, bluetooth is clearly designed for small devices, where
that is neither clean nor sane. Bluez userland is for desktop computers
or higher, and up to v3.4 (I didn't see 3.5 yet) not appropriate when
there is a need to use next to all what bluetooth has to offer,
specially in terms of multitasking.
