      Description

      We assumed that a connection that was being _destroy()ed could not also be inUse. I triggered this invariant by starting a mongod with ssl required and attempting to connect to it without using ssl:

      > ./mongod --dbpath=data/db --sslMode requireSSL --sslPEMKeyFile /etc/ssl/mongodb.pem
      

      >./mongo
