This is local policy, I don't think that it has to be shipped with
emacs. Just give the option of someone specifying it.

GNUTLS_E_AGAIN is returned only if the transport layer function
(recv/send) return -1 and EAGAIN. Usually this is normal behavior and is
enough to loop around them. Do you use non-blocking IO?
