Never bother the application with retries if the transport is blocking.
If a renegotiation take place during normal operation, a
-L<SSL_read(3)|SSL_read(3)> or L<SSL_write(3)|SSL_write(3)> would return
+L<SSL_read(3)> or L<SSL_write(3)> would return
with -1 and indicate the need to retry with SSL_ERROR_WANT_READ.
In a non-blocking environment applications must be prepared to handle
incomplete read/write operations.
=item SSL_MODE_RELEASE_BUFFERS
When we no longer need a read buffer or a write buffer for a given SSL,
-then release the memory we were using to hold it. Released memory is
-either appended to a list of unused RAM chunks on the SSL_CTX, or simply
-freed if the list of unused chunks would become longer than
-SSL_CTX->freelist_max_len, which defaults to 32. Using this flag can
+then release the memory we were using to hold it.
+Using this flag can
save around 34k per idle SSL connection.
This flag has no effect on SSL v2 connections, or on DTLS connections.
