I'm not quite sure why even 1 sync is needed.  :(

I'm not sure what bug this is trying to test; if you need 2 syncs for global 
space stats to accurately reflect the fact that you chopped off the end of a 
block, maybe that's ... still a bug?

Or if it's just the big-hammer question of "does the truncated space *ever* get 
freed?" then maybe umount/remount/check would tell you that more definitively.
