Yes, but I don't do a fsck to recover gjournal- it has a miniscule blurp 
for a nanosecond and prints a message at boot and thats it. Is it the 
same with su+j? If it does then I'll drop gjournal (and the performance 
hit) and I'll use su+j when I jump to 9.0.

I've never done fsck on a gjournal (yet).
