Since updating to 1.1.0 (on Win10 64bit) my server keeps using memory at about ~0.5 Mb per minute. Is there a new setting that must be set or is there a memory leak in 1.1.0?

It's very easy to reproduce:

1. Create a new "ASP.NET Core Web Application" in VS2015 (The wizard will create a 1.0.1 application). Start the application, the "Diagnostics Tools" in VS2015 will show a usage of about ~245.2Mb and will stay there.
2. Now update the app to netcoreapp1.1 (as a further test, leave Microsoft.AspNetCore.Server.Kestrel at version 1.0.0 and it will still not use more memory)
3. Use the new 1.1.0 of Microsoft.AspNetCore.Server.Kestrel and start the "Diagnostic Tool" again: It will start at ~245.2Mb again, but then the "Process Memory" keeps increasing
