Summary
This fixes potential minor goroutine leaks.
Implementation details
Sending to an unbuffered channel without a
select
and without a guarantee that somethingwill receive from that channel, is a recipe for a goroutine leak.
Make the channel buffered to avoid the issue.
Also, with a buffered channel, there is no no need to spin up a new goroutine just to send a
dummy object into it. Instead, just send right after channel creation.
Testing
New tests cover the changes: no
