Reaper thread destroys the socket asynchronously.
zmq_term() can be interrupted by a signal (EINTR).

NAME
----
zmq_term - terminate 0MQ context
SYNOPSIS
--------
*int zmq_term (void '*context');*
DESCRIPTION
-----------
The _zmq_term()_ function shall terminate the 0MQ context 'context'.
Context termination is performed in the following steps:
1. Any blocking operations currently in progress on sockets open within
'context' shall return immediately with an error code of ETERM. With the
exception of _zmq_close()_, any further operations on sockets open within
'context' shall fail with an error code of ETERM.
2. After interrupting all blocking calls, _zmq_term()_ shall _block_ until the
following conditions are satisfied:
+
* All sockets open within 'context' have been closed with _zmq_close()_.
* For each socket within 'context', all messages sent by the application
with _zmq_send()_ have either been physically transferred to a network
peer, or the socket's linger period set with the _ZMQ_LINGER_ socket
option has expired.
For further details regarding socket linger behaviour refer to the _ZMQ_LINGER_
option in linkzmq:zmq_setsockopt[3].
RETURN VALUE
------------
The _zmq_term()_ function shall return zero if successful. Otherwise it shall
return `-1` and set 'errno' to one of the values defined below.
ERRORS
------
*EFAULT*::
The provided 'context' was not valid (NULL).
*EINTR*::
Termination was interrupted by a signal. It can be restarted if needed.
