Immediately open and then close a client handle - why?

Hi,

could someone explain why this is there?

https://github.com/Microsoft/go-winio/blob/master/pipe.go#L337-L339

	// Immediately open and then close a client handle so that the named pipe is
	// created but not currently accepting connections.
	h2, err := createFile(path, 0, 0, nil, syscall.OPEN_EXISTING, cSECURITY_SQOS_PRESENT|cSECURITY_ANONYMOUS, 0)

I think this code was intended to ensure that an instance of the pipe exists, so that you won't see ERROR_FILE_NOT_FOUND. But I think its probably misguided, and that a better approach would be to actually have the listener keep a named pipe instance in standby. I'll be working on code to do just that shortly.

Have a look at PR #80 -- closing that handle turned out to be mistaken, IMO, and is probably ultimately a part of the root cause for #67
