view distribution/scripts/thermostat-command-channel @ 2627:3b82970e37a4
This patch adds a thread to the command-channel process checking that its parent agent process is still
running. On Windows, the death of a parent doesn't kill its child processes.
Once the parent process no long exists, the new thread will exit the current process.
The process watcher thread does not start on Linux.
