We need a file descriptor per D-Bus bus (system and session). But
applications register for (asynchronous) method calls and signals on the
buses. This could happen in several threads, so we need a mechanism how
to distribute incoming events to those threads.

But I would postpone this discussion until after we have resolved the
keyboard issue.

Best regards, Michael.
