Hi Tomo

Do you have plans to return this in the future, once debugged and stabilised?

For me too, as osd-target. It gave performance boost with multiple targets on
same machine. This is because my target is badly written and does sync handling,
no queue, of every thing. Funny that I did not experience problems with it 
during testing, but I'm not running a production system so I might got lucky.

Please tell me your plans so I know if I'll have to fix my backend, one day, or
can get by with this fix.

Thanks
Boaz
