OK, but I still don't understand what problem they solve.

Well, maybe I have an idea.  The one program I used setitimer() in
would core dump if the system was heavily loaded and a second timer
signal occurred before service for an earlier one completed.  Does the
file descriptor interface solve this somehow?
