Add the org.freedesktop.DBus.GLib.Async attribute to your methods and
you'll get async server-side bindings.  These don't return anything and
are passed a DBusGMethodInvocation*, which is used to return a
result/error.  In the bound method you could start a thread or start an
operation and wait for it to complete in the mail loop.  For an example
of use, see eds-dbus, addressbook/libedata-book-dbus/e-data-book.c
