Create memory pressure on private working set. Exit after 30 seconds of inactivity (if on RDP and server hangs)

Program.cs

using System;
using System.Collections.Generic;
using System.Threading.Tasks;

namespace MemoryPressure
{
    internal class Program
    {
        private static List<byte[]> _buffers = new List<byte[]>();

        private static async Task Main(string[] args)
        {
            var totalAllocated = 0;
            var rng = new Random();
            while (true)
            {
                Console.WriteLine("Press enter to allocate 100 MB");
                var to = Task.Delay(3000);
                var tr = Task.Run(async () => await Console.In.ReadLineAsync());
                var t = Task.WhenAny(to, tr);
                if (t.Result == to)
                {
                    Environment.Exit(0);
                }

                var buffer = new byte[100 * 1024 * 1024];
                rng.NextBytes(buffer);
                _buffers.Add(buffer);
                totalAllocated += 100;
                Console.WriteLine($"Allocated {totalAllocated} MB");
            }
        }
    }
}

ReadLineAsync is blocking, need a separate task for delay to work
