The lack of timeout on gethostbyaddr can result in what looks like a  
hung process (to the end user) when it can't quickly resolve an IP.  
This is an issue in IMP message.php via generateFlagImageByHost and  
may be problematic elsewhere.

I've spliced into my install the contributed gethostbyaddr_timeout  
function here:

    http://us.php.net/gethostbyaddr

and might recommend that you do the same.
