I have two request handlers, one of which waits around looking to see if the other one was called (or eventually times out).

I tried something like this but it doesn't work for some reason:

__gshared bool open_cmd = false;

void command(HttpServerRequest req, HttpServerResponse res)
{
	open_cmd = true;
}

void wait(HttpServerRequest req, HttpServerResponse res)
{
	StopWatch sw;
	sw.start();
	while(!open_cmd)
	{
		Thread.sleep(dur!"msec"(25));

		if(sw.peek().seconds > 15)
		{
			res.writeBody("Timed out", "text/plain");
			return;
		}
	}

	open_cmd = false;
	res.writeBody("Recieved command", "text/plain");
}

I saw the `Signal class that says it's for communication between fibers but I don't see a way of having the wait()` timeout.

What's a good way to go about doing something like this?
