Thank you, using ts is really illuminating.
As an incidental query:
I deduce from the look of the snip above that you update Cygwin from
within Cygwin?
I have always done so from within a DOS Command Prompt window,
believing your way to be fatally flawed.
Is your way (much more convenient) ALWAYS OK? What if cygwin1.dll is
itself being updated?

PS Or maybe you are using Windows PowerShell or similar.
