A update prompt appeared for a beta update

Steam Client Beta - May 11

I clicked restart and when steam relaunched this message appears in a separate prompt.
"Work thread 'CContentUpdateContext::m_pCPUh' is marked exited, but we could not immediately join prior to deleting -- proceeding without join"

I have no idea of it's significance or relevance to this beta update so I'm passing it you guys.

Steps for reproducing this issue:

1. Receive Beta Update
2. Click restart steam
3. When steam relaunches a prompt with the error above appears along side with the steam client UI
4. I then restarted steam a 2nd time and the prompt with the error didn't reappear
