> The FailoverTransport.cpp taskRunner includes the FailoverTransport and CloseTransports
tasks.  The FailoverTransport is added first, and appears to always be pending.  This means
the taskRunner always executes the iterate on the FailoverTransport and the CloseTransports
tasks are never run, which causes a build up of socket descriptors (and threads).
> We worked around the issue by adding the CloseTransportsTask to the taskRunner first.
 This allows the CompositeTaskRunner to iterate the CloseTransportsTask when there is work,
and then switching back to iterating the FailoverTransport.
