It would solve half of the problem. Currently, IIRC, the server may
deadlock internally, which means the client times out.
The solution would allow the server not to deadlock internally. But
whether the two programs together deadlock or not is a matter of
implementation detail: whether the binding does a blocking wait with
dbus_send_message_with_reply_and_block or whether it uses an event loop.
If you've got both sides waiting on
dbus_send_message_with_reply_and_block, they'll deadlock.
The only solution to this, that I can see, is to add a DCOP-style tag to
the message, indicating that it is being processed in the context of a

Our first attempt at patching backfired. There are no new patches to be
