 I added a debugging print statement to fsck_ffs, and sent it a SIGINFO
 every two seconds.   Here is the tail of the output, and the tail of the
 truss output.
 
 It seems like it is allocation space for < 10k inodes at a time until it
 fails.  When it fails it is trying to allocate space for 1.5g inodes.
 Is that normal?
