Subject: Net::HTTP.check_response very slow??

I am working on something that uses Net::HTTP to obtain the final url
from a redirected url and, well, it seems really slow. I'm using ruby
1.8.6-p111 and have verified this behavior on OS X, Ubuntu Linux, and
Windows XP.

A sample app is attached and here were my results, comparing the pure
ruby approach to one shelling out to curl...

Tim@thinktank: tmp => time ./url_check.rb
http://ia340903.us.archive.org/0/items/gd90-02-26.sbd.shakedown.451.sbeok.shnf/gd90-02-26d3t05_vbr.mp3

real  0m32.659s
user  0m4.423s
sys  0m3.168s

Tim@thinktank: tmp => time ./url_check.rb --use-curl
http://ia340903.us.archive.org/0/items/gd90-02-26.sbd.shakedown.451.sbeok.shnf/gd90-02-26d3t05_vbr.mp3

real  0m0.754s
user  0m0.030s
sys  0m0.022s

I expected the pure ruby approach to be slower but these results seem
out of line just for a series of http response checks... Any ideas?

Cheers,
Tim
