That's how I had it initially.  However, if I do that then syncing will still be slow for someone who is checking.  I am leaning towards having the default be true.  Then a miner has two choices after adding "-gen=1": either add "-ramhogthreads=n" or add both "-ramhogthreads=n" and "-usesignedhashes=0".  The former, they will sync quickly and mine, the latter, they will sync slowly and mine.  Or they can leave it on for the initial sync, then change the setting again.  A miner will have to be comfortable with changing config files anway.  Any thoughts?
