There is a "concurrency" argument in the constructor of BusAttachment class which limits the number of "method and signal handlers locally executing".
Q1: Does this argument also affect the concurrency of method handlers of the BusObject registered to the BusAttachment?
Q2: If I don't want to bother with synchronization of BusAttachment listeners and BusObjecrt methods, can I just create BusAttachment with concurrency=1 to have _all_ my callbacks/methods/signals handlers executed sequentially? Is there any pitfalls besides potentially slightly lower performance? Our system is single-core anyway, so additional threads does not influence the performance and we don't plan to block the handlers.
Thank you in advance!
