For a single "session" it doesn't matter which is used but if you want an id that is valid across sessions then seems we should be using the system id.

Let me put it a different way. The thread ID issue an old bug that we are not going to address now (and likely not ever). This is a new test for a new command that is exposing the bug (there are other clhsdb commands that could have, but they are not testing in a sufficient manner to expose the bug). Therefore what makes sense now is to have the test work around the issue rather than fail.
