“Yellow alert: Sensors indicate threaded code ahead, Captain.”

Do you really need to use threads? They’re really mainly useful where
you have CPU-intensive tasks. If you are waiting a lot on D-Bus calls,
then doesn’t I/O become the bottleneck in your code?

At the very least, isolate the CPU-intensive threaded stuff onto
threads that don’t make libdbus calls. This should help simplify things.
