The win32PipeListener.Close() hangs if nobody calls Accept()

The win32PipeListener.Close() function attempts to write to an unbuffered channel that has no reader unless someone calls the Accept() function. As a result, the call to Close() hangs indefinitely. The stack trace from the goroutine that is hanging can look like this:

goroutine 84 [chan receive, 5 minutes]:
