[libxml-devel] updated XML benchmarks

Nice.  FYI - you know your script is in the libxml-ruby source tree in 
the script directory?

On my laptop (Thinkpad T60, Core 2 duo, 2GB memory):

               user     system      total        real
rexml    21.747000   0.000000  21.747000 ( 22.145000)
hpricot   4.633000   0.000000   4.633000 (  4.761000)
libxml    0.468000   0.000000   0.468000 (  0.463000)

Its impressive also how quickly Java is.

Aaraon - I added Nokogiri to the script, but it causes a general 
protection fault.  Maybe I'm doing something wrong (just checked code 
into libxml-ruby trunk if you want to look)?

Impressive.
