Summary:                    AMI shows utils.c:1198 ast_careful_fwrite: fflush()
returned error: Broken pipe
Description: 
When sending data to AMI socket, without reading (waiting for) response -
console shows:

ERROR[5148]: utils.c:1198 ast_careful_fwrite: fflush() returned error:
Broken pipe

How to reproduce:
0. You will need php5-cli installed
1. Download 'AMI.class.php' and 'ami-test.php' attached.
2. Edit AMI username/password in 'ami-test.php'.

NOTE: To revert back to a 'normal' behaviour, change line 72 of
'AMI.class.php' to: 'public $sync = true;'

---------------------------------------------------------------------- 
Our application is written in Perl and is connecting via the Net::Telnet
directly into the AMI. We have a script that spawns child processes. The
children connect to the AMI, issue a command (mostly originate), wait 4
seconds for a response, and then disconnect and exit. If the children get a
response they puts them into a log table in our database. We are seeing
these errors appear in the CLI on 1.4.23.1 with only about 12 calls. In
1.4.21.2 we do not see this issue at all, and we place 120 calls via this
method regularly. Something must be slowing Asteirsk's response to our
commands down or blocking them internally.
