Restart only works once

When you hit the 'restart' button in VSCode, CodeLLDB sends a disconnect command to the gdbserver, then disconnects and reconnects. That is fine and I configured that to restart the VM. However the *second* time you do it it sends a kill command instead. I'm not sure why; could be a bug in CodeLLDB.

Start by reproducing the behavior from the VSCode restart button with CodeLLDB and the gdbserver: compare the first and second restart sequences, especially the disconnect and kill commands. Done means repeated restarts consistently use the configured disconnect-and-reconnect behavior without sending kill.
