Walkthrough

In checkListeners, the expected data event listener count for a non-destroyed socket was changed from 1 to 0.

Changes

Test assertion fix

Layer / File(s)	Summary
Socket data listener assertion test/addons/nsolid-tracing/test-http-agent-keepalive.js	checkListeners now expects zero data listeners on a non-destroyed socket instead of one.

Estimated code review effort: 1 (Trivial) | ~2 minutes

Poem

A rabbit counted listeners near and far,
Found one where zero should clearly be तार?
With a twitch of the nose,
The assertion now knows,
And the socket sits quiet as a star.
