To me "table" doesn't imply "array". It's just some kind of
data-structure that keeps the elements at hand. It can be a list, an
array, a tree, a has-table, you name it.

Note that if we use integers instead of a new type, we can't free
those structs when the Lisp code loses the last reference to the
file-watcher.

Why is that needed?
Can you give a precise description of your alist?
