 BIO_destroy_pair() destroys the association between two connected BIOs. Freeing
 up any half of the pair will automatically destroy the association.

+BIO_shutdown_wr() is used to close down a BIO B<b>. After this call no further
 writes on BIO B<b> are allowed (they will return an error). Reads on the other
 half of the pair will return any pending data or EOF when all pending data has
 been read.
