[zeromq-dev] Messages not delivered

There are a lot of factors and variables involved.

First let's start with the basics...

- 0MQ version and which language binding you are using if any, along with
respective version numbers.
- Operating systems involved.

Now in 0MQ you could send messages in two ways, either you send a message
asynchronously or synchronously, in the former case if you pushed 10 messages in
the asynchronous queue without blocking on the send() operation, it is very
likely that you terminated the client before some messages hit the wire. A good
indicator for this phenomenon is that you receive what seems to be a random
number of messages at the receivers end sporadically over the number of client runs.

Also code snippets would help clarify the problem.
