How to kill whole application if child thread raises an exception?

[rikki cattermole via Digitalmars-d-learn]

Basically when you spawn a thread giving the function, you pass it 
through another function which will catch any exceptions not normally 
caught.

Of course this really should be the default behavior but somebody else 
may be more of a help here.

And it is pseudo code, so please don't expect it to 100% work as I have 
written it.

```D
void entryPoint(alias func)() {
	try {
		func();
	} catch (Exception e) {
		import std.stdio;
		writeln(e.toString());
	}
}

void main() {
	auto tid = spawn(&entryPoint!someFunc);
	// ...
	
}
```
