No, you've got the situation backwards. The situation doesn't involve 
any hanging, it involves possible data loss of the last packet. We will 
make a single attempt to do the final write (via calling SSL_shutdown), 
and if it fails to write because of some transient error, we have no 
way to know, so we close the connection anyways, even though we 
should've retried.
