	fn is a string, so feeding the same value back in wouldn't help.

	The real problem here was a runtime failure in one of the functions 
that is very unlikely to occur where this program is actually deployed. 
  I just wanted to make sure that when a failure did occur, it was dealt 
with properly.  The ``unknown error'' part was my biggest concern, 
because I really didn't have a way to know what went wrong.

	The answer to my main concern was the Printexc module:

let should_process fn =
     try
         (ends_with fn ".") && (is_new_enough fn) && (not (is_gzip fn))
     with x ->
         print_endline("Unknown error determining whether to process " ^ 
fn);
         print_endline (Printexc.to_string x);
         false
