Doesn't this need to export the variable so that credential-cache can
see it?

This runs the full suite of tests twice (once here, and once for the
original helper_test invocation you left below). Shouldn't we just do it
once (making sure that $XDG_RUNTIME_DIR is respected)?

I wondered if this might be racy. credential-cache tells the daemon
"exit", then waits for a response or EOF. The daemon sees "exit" and
calls exit(0) immediately. We clean up the socket in an atexit()
handler. So I think we are OK (the pipe will get closed when the process
exits, and the atexit handler must have run by then).
But that definitely was not designed, and is just how it happens to
work. I'm not sure if it's worth commenting on that (here, or perhaps in
the daemon code).
