An enhanced MySQL database driver. With support for async operations and threaded database access.
Added Encoding awareness for Ruby 1.9. Convert all data to default external encoding ( merged from http://github.com/lsegal/mysql-ruby )

== Using
to use within rails
add require 'mysqlplus' to the top of environment.rb
this instantiates the Mysql class that you can use.
and it will automagically use async_query instead of query, so it's a drop in replacement.
Same with other scripts that want to use it--just require 'mysqlplus' BEFORE you require 'mysql' and it will
load the asynchronous version, then ignore the sequent require 'mysql' call.
== Other helpful mysql utilities:
slim attributes http://slim-attributes.rubyforge.org/ boosts mysql speed by using arrays instead of hashed lookup.
Hash extension gem also results in speedups when used: http://blog.chak.org/2008/02/09/speeding-up-activerecord-with-hashes-take-2/

TODO_LIST

TODO list:
Is there a quick, cheap, easy way to test for writability so we don't have to use select itself? Does select take any time that it's worth looking into this?
Some of the tests currently might "think" they are using the ruby select but in reality be using the C select.
gc_disabled is unused
if they call get_result twice consecutively it should blow (and maybe already does).
mingw support
add slim attributes right in there :)
