[PATCH 0/1] MR3648: server: Set the default thread exit code to 1.

[Brendan Shanks (＠bshanks)]

The default exit code is only used when a process is killed by the system or through a signal.
These are exceptional cases where exit code 1 (killed by Task Manager) is more appropriate than the normal termination code of 0.

Chromium does not restart helper processes that exit with code 0 (see [kill.h](https://source.chromium.org/chromium/chromium/src/+/main:base/process/kill.h...)), with this fix they are restarted when killed by the system or by a signal.
