No suitable finish event for pipe

[polomsky]

• Version: 8.7.0
• Platform: linux
• Subsystem: stream

There is no way to detect that stream.pipe is finished. There is an event finish for writable streams, but it is unusable for specific usecases (writing to process.stdout or process.stderr).
And if I understand it correctly, finish event is not emitted when pipe is called with {end: false}. So I can not simply pipe multiple read streams to the single write stream.

After investigation I have found that event unpipe can be probably used for that purpose. Sadly it is not in the 6.x version. Fixed by #11876

Seems like this has been addressed by the OP but if not, please feel free to re-open. Not sure this would get back-ported to v6.x, if it hasn't been already.
