When we are children, we are told that sharing is good. In the

amount of sharing, then it can take longer to delete a set of files
since the mutual references create a "hot spot" which must be
updated sequentially.
Y'know, that is a GREAT point. Taking this one step further then -
does that also imply that there's one "hot spot" physically on a
disk that keeps getting read/written to?
Also, copy-on-write generally means that physical location of updates
is ever-changing.
