Some do, some don't.

However, removing all the empty dirs, even though they had empty files
in it, saved me 30 meg on a gcc checkout.

This was on reiserfs
It's about 60 meg on ext3

So we should strive to not create files until we need them, assuming we
don't pay performance for it.

I also imagine stat of non-existent file is faster than stat of empty
file :)
