actually there has been another bug in 2.8.0 and 2.8.1 which was also
triggered when the push function returned EAGAIN:

The fix is in
http://git.savannah.gnu.org/gitweb/?p=gnutls.git;a=commitdiff;h=c7e003ad9427c655a1b559baff1239a2c1907f32

The GnuTLS developers also added a test case that should hopefully
detect future problems like this, see tests/mini-eagain.c
