Note that putting '/var/cache/e2fsck' in a memory filesystem is aprox. 3
times faster ;-)

Making some fast test with e2fsck v1.40.10 appears that is a bit faster
than v1.40.8, last version improves this feature? Anyway, finally I had to
cancel the process..

# ./e2fsck -nfvttC0 /dev/sda4
e2fsck 1.40.10 (21-May-2008)
Pass 1: Checking inodes, blocks, and sizes
/dev/sda4: e2fsck canceled.                                                
     

/dev/sda4: ********** WARNING: Filesystem still has errors **********

Memory used: 260k/581088k (183k/78k)
