I am still missing one thing - dropped provider is not marked as failed 
RAID provider and is accessible for anything like normal disk device. So 
in some edge cases, the system can boot from failed RAID component 
instead of degraded RAID. This can cause data loss or demage.

Is it possible to fix it by something like your geom-events, or should 
it be done in each GEOM RAID class separately?

But after all, I realy appreciate your work in this area! I hope I will 
have time to test it soon.

Thank you!
