You have to close file handles as well (even if you use the block form
of File.open you take care of this in a way).

No, because you can make that part of the library.  At least you can
built your library in a way that it will invoke a cleanup hook which
you define as empty method for application specific cleanup so users
of the lib do not have to but can add cleanup functionality. Cleanup
of the framework is done automatically of course. Note that there are
already libraries that abstract such a scenario.
