recovering crashed large (139M+ row) MyISAM table

A server I am using MySql on had a power outage and a very large MyISAM table that I have was marked crashed by MySQL.

I am currently using myiasmchk -r -q on the table but it has literally been running now for 36 hours nonstop without finishing.

Is there a faster process to do this? Is there a way to make a copy of the table, mark it uncrashed, and see if it is ok? Are there any plans to add spatial extensions to InnoDB (or any of the other transactional FS) so we can avoid this totally crazy recovery time?

Or more generally, how does anyone run in production with MyISAM with big tables and avoid this?

Thanks,
Tim
