This one works fine for me in Windows with VisualD and DMD 
2.070.0:
------------------------------
import std.concurrency, std.stdio, std.exception;

void main() {
	auto low = 0,
		high = 100;
	auto tid = spawn(&writer);

	foreach (i; low .. high) {
		writeln("Main thread: ", i);
		tid.send(thisTid, i);
		enforce(receiveOnly!Tid() == tid);
	}
}

void writer() {
	scope(failure) return;
	for (;;) {
		auto msg = receiveOnly!(Tid, int)();
		writeln("secondary thread: ", msg[1]);
		msg[0].send(thisTid);
	}
}

------------------------------

Just one line added to writer() in order to catch OwnerTerminated 
exception and end the thread silently. Original version produced 
an error when main thread finished before the writer thread.
