Description:
------------
When using gethostbyaddr with an IP it will return a host name just what
we want. However, if there is no host name to return it stalls and takes
20-30 seconds PER IP lookup. If it CAN return a host name it does so in
<1 second.

Example - I can loop through 5 IPs that resolve to hostnames in .7
seconds. This includes database calls, and updates.

Example 2 - I can loop through 5 IPs that DO NOT resolve to hostnames in
3 minutes!!! 

This needs to be fixed, or a second parameter option for max look-up
time per-ip.

gethostbyaddr(IP,Max_Execution_Time) as example.
