fwrite infinite loop - diff provided to fix issue

[GoogleCodeExporter]

What steps will reproduce the problem?
1. start an amqp server
2. start a process which polls the amqp server for messages in a queue
3. shut down the amqp server

What is the expected output? What do you see instead?
I expect to see the "throw new Exception("Error sending data")" get executed, 
but in php 5.3.8 (cli) I get a repeating error which quickly fills up my 
log/disk with this:
Notice: fwrite(): send of 12 bytes failed with errno=32 Broken pipe in 
/var/www/sites/oxygen/library/Lava/Amqp/php-amqplib/amqp.inc on line 481

What version of the product are you using? On what operating system?
I'm using centos 5.5, php 5.3.8 (cli) and php-amqplib 0.8

Please provide any additional information below.
Here is a diff that I made so that when fwrite returns 0 bytes written an 
exception is thrown and we don't get stuck in the loop.
