It's an interesting question :-)

It's somewhat workload dependent but personally I think your solution sounds 
reasonable.  If you have time, you might like to try distributing domains 
across both threads and seeing if it makes any difference.

Unless your domains are heavily loaded, you won't see much difference anyhow.
