async prepared statements

[fw42]

Is it currently possible to run prepared statements asynchronously?

It seems like neither the prepare nor the execute methods take a async parameter (like query does) and setting query_options[:async] = true also doesn't seem to have an effect.

Is this a known (intended?) limitation?

This should be resolved in mysql2 0.5 with PR #912 and improved by PR #958.

So async is not supported, but :stream is now supported for prepared statement results in mysql2 0.5.x.
