[zeromq-dev] Are bindings supposed to set linger on implicit close/destroy?

The zguide states at the end of "Making a Clean Exit":

Yet I noticed the pyzmq bindings do not seem to follow this convention and
scripts that do not explicitly set linger themselves hang.  The pyzmq devs
closed this as a non-issue:


Conversely, both the czmq and jzmq bindings do set a low linger:


So should this be considered a bug in pyzmq, and as a bindings author
should I follow the convention of setting a low linger?

Thanks much,
