Description
As we will very soon have both osmo-bsc and osmo-mgw opening timeslots on the same E1 lines, let's make sure we fail properly if two clients try to concurrently open the same E1 timeslot.
I just checked the DAHDI source: DAHDI fails any second or further open() of the timeslot device with -EBUSY.
