once again - read more carefully :)

I am NOT talking about background fsck which is implemented in FreeBSD and 
i turn this off.

I am talking about just not doing fsck of every filesystem after crash. 
And doing it within same day but when pause is not a problem.

This is legitimate method with UFS+softupdates.

Assuming hardware never fails is certainly wrong

No it isn't. Sorry if i wasn't clear enough to explain it.
