I don't know for sure how the kernel and ext3 handle these things but  
I would *think* that the system is smart enough to not block on a  
delete. I'd think the file would be marked as deleted in the cache  
and the actual "deletion" (really just marking space as available)  
would be carried out when IO was available.

Or is that what makes the newer filesystems "better" ?

I've certainly never noticed any delays even when I delete a dozen or  
more shows rapidly, If I had I would have switched to another FS  
(maybe).
