Well, the basic idea is that Mercury's `io' module, eventually to become
`std.io', should provide roughly the same kind of services as C's <stdio.h>.
<stdio.h> does provide a `remove()' function for removing files.

Anything which provides services that require additional operating system
support above and beyond what is provided by ANSI/ISO C is likely to be less
portable, and so it's probably better to put such services in a different
module, so that it's easier to avoid accidental dependencies on such services.

Does that seem like a reasonable basis for classification?
