Sorry, I forgot to do a opcontrol --reset between sessions. The updated
profile (not great since this towards the end of my operations which isn't
great) is as follows:

422243 55.3991 hostip.c:0 libcurl.so.4.1.1
hostcache_timestamp_remove
204745 26.8629 (no location information) libcurl.so.4.1.1
Curl_hash_clean_with_criterium
39162 5.1381 (no location information) libcurl.so.4.1.1
Curl_hash_pick
32256 4.2320 (no location information) libc-2.7.so (no
symbols)
14293 1.8753 (no location information) libcurl.so.4.1.1
Curl_hash_add
6557 0.8603 inffast.c:70 libz.so.1.2.3.3
 inflate_fast

So there's still a lot of time spent in just a couple of methods. Any
thoughts for improving this?
If I increase the size of the DNS cache or eliminate it entirely (which I
don't need since I'm using a local recursing and cache dns server) would I
see a benefit? Actually... I can just try that and get back to you guys ;)
