[zeromq-dev] HWM default

Hi all,

I though of changing the default value for HWM to say 1000 in 0MQ/3.0.

The rationale being that unlimited buffer is a stability threat. In 
other words, default socket when overloaded or DoS'ed will run out of 
memory and crash the application rather than behave decently.

So, I think, we should offer stable behaviour as default and leave it to 
user to opt out if infinite buffer is really what he wants.
