-The functions described here were used to free the error queue
-associated with the current or specified thread.

-They are now deprecated and do nothing, as the OpenSSL libraries now
-normally do all thread initialisation and deinitialisation
-automatically (see L<OPENSSL_init_crypto(3)>).
+ERR_remove_state() frees the error queue associated with the specified
+thread, identified by B<tid>.
+ERR_remove_thread_state() does the same thing, except the identifier is
+an opaque pointer.
