[jdev] Multiple IQ stanzas in one "socket read"

[Peter Mount]

Yes it is possible as it's an xml stream not a packet based protocol.

A socket read simply means you have data available to be read.

So in this instance the server had two stanzas available and they got sent
together.

The opposite is possible. You could have a stanza that's too large so it
takes multiple reads to receive the stanza.
