host_name and service_description examples

[Andreas Ericsson]

I've made some corrections to the benchmark code, and a couple of cheap 
optimizations. For those who want to test it for themselves (a whopping 
3 downloads so far ;), I suggest you leech the new version from 
http://oss.op5.se/nagios/nagios-hash.tar.gz and give it a shake.

Ethan; If it's allright with you, I'll go ahead and implement Paul 
Hsie's hash. It looks up 1074600 hostname strings in 358msecs with the 
current table-size of 1024 buckets (compared to 987msecs for the 
additive hash currently in use). I'd also suggest wasting some memory 
here. Upping the hash-table size to 16384 buckets (64Kb on 32-bit archs) 
cuts another 40% off the average lookup time while staying fairly 
friendly to the hardware.
