Well, we don't need to buffer such large amount of data. But we didn't
know that GnuTLS buffered ALL the corked data, because the documentation
to gnutls_record_cork() used to imply otherwise, i.e:

  All queued records will be sent when gnutls_uncork() is called,
  **or when the maximum record size is reached**.

(**emphasis** added)

Our application was just sending gigabytes of data while GnuTLS was
corked. We assumed that GnuTLS would buffer at most the maximum record
size number of bytes.
