+ * given size (list->chunklen); other sized chunks are freed and malloced.
+ * This doesn't help much if you're using many different SSL option settings
+ * with a given context. (The options affecting buffer size are
+ * max_send_fragment, read buffer vs write buffer,
+ * SSL_OP_MICROSOFT_BIG_WRITE_BUFFER, SSL_OP_NO_COMPRESSION, and
+ * SSL_OP_DONT_INSERT_EMPTY_FRAGMENTS.) Using a separate freelist for every
+ * possible size is not an option, since max_send_fragment can take on many
+ * different values.
+ *
+ * If you are on a platform with a slow malloc(), and you're using SSL
+ * connections with many different settings for these options, and you need to
+ * use the SSL_MOD_RELEASE_BUFFERS feature, you have a few options:
+ * - Link against a faster malloc implementation.
+ * - Use a separate SSL_CTX for each option set.
