Summary:                    ERROR[5003]: channel.c:2043 __ast_read: ast_read()
called with no recorded file descriptor.
Description: 
Performed an upgrade from 1.4.22 to 1.4.24 running on CentOs 4.  Used the
same "slim" configuration that I used in 1.4.22, which worked fine.

Calls are processing, but connecting to the console gets the following:

[Mar 23 13:08:05] ERROR[5003]: channel.c:2043 __ast_read: ast_read()
called with no recorded file descriptor.
[Mar 23 13:08:05] ERROR[5003]: channel.c:2043 __ast_read: ast_read()
called with no recorded file descriptor.

This repeats continuously.  If I issue a show channels, I get some output
and it seems to stop the ERROR messages, though it seems the "show
channels" does not complete.  You can get the CLI command and * will still
be trying to spit out a few channels below it.

The system load is also very high (2.38 with 50 or so concurrent calls),
though CPU usage is low... it must be coming from somewhere else. 
Typically this load under 1.4.22 would show perhaps a 0.2 or 0.3 load.

    Only do the chan->fdno check in ast_read() in a developer build.
    
    I changed this check to only happen in a dev-mode build.  I also added
a
    comment explaining what is going on.  I also made it so that detection
of
    this situation does not affect ast_read() operation.
