Something like that might work... it'd delay the first write a bit, 
but probably would be implemented with just a few lines of code 
in raidstrategy()...  (hm... actually, I see now that 
rf_markalldirty() is called in a few other places too, not just on 
the first open... I need to think about why that might be, and 
whether or not those other calls are "extra" and can be removed... )
