I am getting back to this select stuff. So I have a question, would you
agree if the select support was made configurable, but if when this
support was enabled, support for select was added to vanilla
rtdm_event_t and rtdm_sem_t ? This would ease maintenance, since it
would avoid a lot of code duplication, without adding to much overhead
in my opinion (an empty list test when signaling the objects).

Ok, I had a look at the CAN stack, if I understand correctly when
receiving, the recv_sem defined in rcan_socket.h is used, and when
sending, the tx_sem defined in rtcan_dev.h is used. Can you confirm this
