I believe, though, that this would explain at most a factor of 2 of "write 
expansion" (user data getting pushed to disk once in the intent log, then again 
in its final location). If the writes are relatively large, there'd be even 
less expansion, because the ZIL will write a large enough block of data (would 
this be 128K?) into a block which can be used as its final location. (If I'm 
understanding some earlier conversations right; haven't looked at the code 
lately.)
