Fix Automattic/mongoose#6249
In addition to the changes in #1685, I put together a test that fails when
mongos.js
is unchanged. Should make it clear why this change is necessary.As far as mongoose is concerned, the 'close' event is what matters, so I'd be open to leaving the 'timeout' and 'error' events as
once()
if that helps address any concerns.
