This source code is now available online at
<https://github.com/ldo/slow_dbus_server> and
<https://gitlab.com/ldo/slow_dbus_server>. I have done a few minor
updates, including an important bugfix to the argument-extraction code
for the count_primes method: I forgot to terminate the
dbus_message_get_args call with a DBUS_TYPE_INVALID arg, so it was
always returning an error, which I was ignoring anyway. Not any more.
