Minimal test case: 

void main()
{
        import std.concurrency : Generator, yield;
        import std.stdio : File, writeln;

        auto f = File("/proc/sys/vm/max_map_count", "r");
        ulong n;
        f.readf("%d", &n);
        writeln("/proc/sys/vm/max_map_count = ", n);
        foreach (i; 0 .. n + 1000)
        {
                if (i % 1000 == 0)
                        writeln("i = ", i);
                new Generator!int({ yield(1); });
        }
}
