stdlib.exit()

[Minas]

I don't know about the runtime, but destructors are not called 
(not sure about module destructors)

import std.stdio;
import std.c.stdlib;

void main()
{
	S s;
	
	exit(-1);
}

struct S
{
	~this()
	{
		writeln("destructor");
	}
}

This prints nothing, meaning that the destructor wasn't called.

But why do you want destructors to be called when you call 
exit()? You are exiting in an "abnormal" way anyway.
