• closed registry handle in init

Thank you for your contribution!

Let me check the intent of this PR: is the intent to change the quitChan to wait for the quitChan to close on defer with select in order to prevent goroutine leaks?

If so, then indeed the goroutine continues to remain in the current implementation, and this PR seems to solve that.

Hi @shirou
When the context is done before or during PartitionsWithContext, the goroutine will still be alive because it cannot send to the channel. I intended to prevent this kind of leak scenarios. Also, I used a quit channel explicitly instead of using context's Done channel in the gouroutine to make it more robust.

It could be resolved using a buffered channel as well however my fix seemed to be an idiomatic approach with channels.

Lastly, all parameter is not used in PartitionsWithContext. I don't know the background of this intention but if it seems to be a bug I can also create another PR for that.

Thank you for your explanation. I understood your intention and I agree with you. Thank you very much.

As for the all argument, we don't use it in the Windows implementation, but we use it on other platforms such as Linux.
