Subject: avoid curve test to hang on ppc64 architecture
Date: Wed, 28 Jan 2015 13:46:07 +0100

Avoid curve test to hang on ppc64 architecture
At least no problem anymore with those commits:
    Merge pull request #101 from hintjens/master
    Problem: issue #1273, protocol downgrade attack
    Merge pull request #100 from hintjens/master
    Problem: zmq_ctx_term has insane behavior by default

extracted from https://github.com/zeromq/zeromq4-x.git
===
$git diff -u v4.0.5 b6e3e0f601e2c1ec1f3aac880ed6a3fe63043e51 >/tmp/x
and remove the change of version (to keep 4.0.5)

+WARNING
+-------
+
+As _ZMQ_LINGER_ defaults to "infinite", by default this function will block
+indefinitely if there are any pending connects or sends. We strongly
+recommend to (a) set _ZMQ_LINGER_ to zero on all sockets and (b) close all
+sockets, before calling this function.

 RETURN VALUE
 ------------
 The _zmq_ctx_term()_ function shall return zero if successful. Otherwise
