Description

Every unit test that involves use of a connector leaks the connector and a related qd_timer_t.  These leak warnings overwhelm other warnings in the test output.

The qd_connector_t is reference counted.  It also contains a qd_timer_t.  From initial debug the reference count is never dropping below 1.

It appears that every time the timer is scheduled the refcount is incremented.  This appears to be an attempt to prevent the deletion of the qd_connector_t while the timer is outstanding.  This appears likely to be the source of the outstanding ref count.
