if epics.PV() calls the connection callback before the self._cond is created the error is thrown:
File "/python/fsmscan/.venv/lib/python3.10/site-packages/smlib/io.py", line 61, in concb
self.lock()
File "/python/fsmscan/.venv/lib/python3.10/site-packages/smlib/io.py", line 53, in lock
self._cond.acquire()
AttributeError: 'epicsIO' object has no attribute '_cond'. Did you mean: '_conn'?
in case of loader use it is already killed in killAll()

The
epicsIOrace condition appeared after the fsm was started, stopped and then restarted.
