Can you amend the commit message so it matches our guidelines? using is not an imperative verb, I suggest something like stream: fix deadlock when cloning webstreams

node/doc/contributing/pull-requests.md

Lines 170 to 172 in 1149d6b

	* be prefixed with the name of the changed [subsystem](#appendix-subsystems)
	and start with an imperative verb. Check the output of `git log --oneline
	files/you/changed` to find out what subsystems your changes touch.

There seems to be a problem with FinalizationRegistry, so please wait for that to be resolved.

@tsctx Can you elaborate? (just use request change to block merge)

Appreciate the work on this but this isn't the correct fix. The issue is the fact that cloned ReadableStream and WritableStream instances use a MessageChannel under the covers to communicate. The MessagePorts for each need to be unref'd in order to allow the process to exit. I'll have an alternative PR opened shortly.
