Bug description

$ for _i = 0 to 10000; do try ignore (Digest.file "." : string) with e -> Printf.printf "%s\n%!" (Printexc.to_string e); done;;
(Sys_error ".: Too many open files")
(Sys_error ".: Too many open files")
(Sys_error ".: Too many open files")

Digest.file should catch exceptions and close the channel, for instance:

let file filename =
let ic = open_in_bin filename in
let d =
try channel ic (-1)
with e -> close_in ic; raise e
close_in ic;
