[Tux3] forward logging and NVRAM

[timothy norman huber]

Daniel,

Several weeks ago, during a discussion over coffee, you mentioned a  
rather intriguing optimization- by writing the start of the forward  
log chain to NVRAM rather than disk, you avoid a disk seek and write  
transfer for each forward log chain.  i believe there was another  
motivation that had to do with avoiding traversing the entire volume  
in case of a crash.  Was this design feature to overcome lame fsck  
performance?
