Description:
Single call to ALTER TABLE t ENABLE KEYS usualy takes hours in my case (depends on table size, can also take days). It would be cool to get somehow info on percentage of indicies already re-constructed (in separate thread or call-back), so I can display it to the end-user.

How to repeat:
ALTER TABLE t ENABLE KEYS

Thank you for a feature request. You pointed out only one of the long-running statements. I believe, that for any statement that works more than, say, 10 seconds, there should be a way to monitor it's progress. Oracle has similar feature for all it's internal long-running processes. So, I think, it will be useful to add something similar in future versions of MySQL 5. But it is not a simple thing to do, so don't expect it to be implemented soon.
