+/* On some platforms, malloc() performance is bad enough that you can't just
+ * free() and malloc() buffers all the time, so we need to use freelists from
+ * unused buffers.  Currently, each freelist holds memory chunks of only a
+ * 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.
+ *    - Improve this code.
