The main loop is only used in dbus-daemon itself, and maybe in some of
the utilities; it's not used by libdbus. So thread safety doesn't
libev is a little not-cosmetic but it's certainly far more functional,
performant, and widely-tested than the ad hoc thing I wrote in
dbus-mainloop.c, and almost certainly better than anything anyone else
would write in a reasonable amount of time, too. It's also already
done all the work for use-assorted-alternatives-to-poll. node.js has
banged the hell out of libev.
What I'd do is encapsulate it in a file with a nicer API (maybe even
the existing mainloop API or one like it) so it doesn't leak all over
the codebase. But it's a very pragmatic thing to use.
