I recently ran into the same issue. I actually intended to see if this
can be changed without any negative consequences. The IOC shell code
actually handles "exit" a bit weird - it just returns rather than
shutting down [1]. Returning is not sufficient since IOC applications
usually contain something like

iocsh(argv[1]);
iocsh(NULL);

The first line processes the st.cmd file and returns when it finds an
"exit" line. The second line results in an interactive shell session.

Unfortunately iocStats is not available with the softIOC executable.

My use case:

iocInit()
system('python3 test.py') # writes test output to test.tap
exit()

We are running something like this on our CI server.
