/**
* Used to intercept shutdown attempts by other code - some mods have anti-modification code
* which is rather annoying as it makes them impossible to patch. This is used to find where that code is
* and disable it.
* Currently in general unnecessary as code is patched at runtime, and these mods detect jar signature violations
* Additionally, this ensures that even in the case of a Runtime.halt(), logging will be flushed to disk.
