* Pass callback to client.end
* Add test for pool.end method
* fix: remove excessive _pulseQueue call
* fix: context problem
* fix: test resolve should be called when the last client is removed
* fix: wait for pool.end()
Because when you don't pass a callback to .end() it always returns a promise
* fix: handle idle timeout test data race
