Interesting. If I restart while launched from lldb, I get the below.
It happens right away and it doesn't actually restart. This is not the
behavior I see if I launch it normally or in xcode. I should note that
occasionally when I restart Emacs it just quits and does not restart.
I have to restart it manually. Perhaps this is all connected to the
issue you're suggesting.
