Test failure: System.Net.Tests.HttpListenerResponseHeadersTests.KeepAlive_SetDisposed_ThrowsObjectDisposedException

[BruceForstall]

With:

COMPlus_TailcallStress=1
COMPlus_TieredCompilation=0

This test hangs. Fails on Windows x86, x64 and arm64 (at least).

This is release libraries, checked coreclr.

This is just the tip of the iceberg. There are many other hangs and failures in this assembly if you get past this one (e.g., by disabling just this one test).

The bad tail call for System.Net.Tests.HttpListenerResponseHeadersTests.KeepAlive_SetDisposed_ThrowsObjectDisposedException is the same as in #38887 (comment)

runtime/src/libraries/System.Net.HttpListener/src/System/Net/Windows/HttpListener.Windows.cs

Lines 307 to 321 in b39c698

	private void AttachRequestQueueToUrlGroup()
	{
	Debug.Assert(Monitor.IsEntered(_internalLock));
	// Set the association between request queue and url group. After this, requests for registered urls will
	// get delivered to this request queue.
	Interop.HttpApi.HTTP_BINDING_INFO info = default;
	info.Flags = Interop.HttpApi.HTTP_FLAGS.HTTP_PROPERTY_FLAG_PRESENT;
	info.RequestQueueHandle = _currentSession.RequestQueueHandle.DangerousGetHandle();
	IntPtr infoptr = new IntPtr(&info);
	SetUrlGroupProperty(Interop.HttpApi.HTTP_SERVER_PROPERTY.HttpServerBindingProperty,
	infoptr, (uint)Marshal.SizeOf(typeof(Interop.HttpApi.HTTP_BINDING_INFO)));
	}

We are passing a pointer to a local infoptr (points to info) to the call to SetUrlGroupProperty. So it's a tailcallstress issue.
