Under what circumstances does exits("All done.") will
print the string? For program termination/abort purposes
it seems to behave like exits(nil).

Never. Just like exit(1) in Unix never prints "1".
You can get the exit status from wait (or by echo $status
in the shell). If you want to print something too, use sysfatal.

Except for setting the exit status, yes it does.

sure but that's acme printing the string.
exits() will never print a string.
