Because you may nedd to cleanup for completely unrelated parts of your
scripts.

That's what I did to solve the problem then. Actually I even have built a
registration table that would handle removing registration entries and
would be able to pass context to each of the registered shutdown functions.

One of the problems is that I had to resort to global variables. That's
fine as long I don't use somebody else's code that uses the same global
variable names.

Another problem is if you borrow code that also sets registers a shutdown
function overriding yours or vice versa.

It may happen and you might not be aware of the clash if you don't study
throughly the code you are borrowing.

PHP could be more flexible here if you reckon that these situations might
be problematic. Usually I don't borrow much code, but I am certain tha a
lot of people that is not skilled enough just borrow code from everywhere
to solve their problems and are not aware of these situations.
