NullReference exception while shutting down Kestrel based application

[Praburaj]

I have seen this several times now on shutting down an application using Kestrel.

Unhandled Exception: System.NullReferenceException: Object reference not set to
an instance of an object.
   at Microsoft.AspNet.Server.Kestrel.Networking.UvHandle.ReleaseHandle()
   at System.Runtime.InteropServices.SafeHandle.InternalFinalize()
   at System.Runtime.InteropServices.SafeHandle.Dispose(Boolean disposing)
   at System.Runtime.InteropServices.SafeHandle.Finalize()

Launch the app, make a few requests to the server and after a while stop the app by pressing enter in the command prompt.

Seems to be a duplicate of / related to #9.

Note, I can consistently repro this if I don't close the browser before stopping the application.

Dupe of #9
