If I call ExecuteNonQuery() in a timer event callback in a console application, it hangs. Why is that

class Program
{
static SqlConnection conn = new SqlConnection("Integrated Security=SSPI;Persist Security Info=False;Initial Catalog=NONEOFYOURBISUINESS;Data Source=localhost");
static void Main(string[] args)
{
NativeMethods.MEMORYSTATUSEX mem = new NativeMethods.MEMORYSTATUSEX();
NativeMethods.GlobalMemoryStatusEx(mem);
Console.WriteLine("{0} bytes", mem.ullAvailPhys);
System.Timers.Timer aTimer = new System.Timers.Timer();
// Set the Interval to 2 seconds (2000 milliseconds).
aTimer.Interval = 1000;
aTimer.Enabled = true;
// Hook up the Elapsed event for the timer.
aTimer.Elapsed += new ElapsedEventHandler(OnTimedEvent);
Console.ReadLine();
}
private static void OnTimedEvent(object source, ElapsedEventArgs e)
{
NativeMethods.MEMORYSTATUSEX mem = new NativeMethods.MEMORYSTATUSEX();
NativeMethods.GlobalMemoryStatusEx(mem);
SqlCommand cmd = new SqlCommand(
"INSERT INTO Observation (StatisticType, StatisticObserved, StatisticValue) VALUES (1, @When, @AvailPhys);\n" +
"INSERT INTO Observation (StatisticType, StatisticObserved, StatisticValue) VALUES (2, @When, @AvailPageFile);\n" +
"INSERT INTO Observation (StatisticType, StatisticObserved, StatisticValue) VALUES (3, @When, @AvailVirtual);\n" +

DateTime dt = DateTime.Now;
cmd.Parameters.AddWithValue("AvailPhys", mem.ullAvailPhys);
cmd.Parameters.AddWithValue("AvailPageFile", mem.ullAvailPageFile);
cmd.Parameters.AddWithValue("AvailVirtual", mem.ullAvailVirtual);
cmd.Parameters.AddWithValue("AvailExtendedVirtual", mem.ullAvailExtendedVirtual);
cmd.Parameters.AddWithValue("When", dt);
cmd.ExecuteNonQuery();
Console.WriteLine("Inserted {0}", dt);
}
