Most likely, %timings does not contain what you think it does.

Maybe inspect it before every iteration:

use Data::Dumper;

...

for (;;) {
    warn "Next iteration:";
    warn Dumper \%timings;
    foreach my $item (sort (keys %timings)) {
        warn "Processing [$item]";
        do_stuff(); # changes data, not keys, no deletes
    }
}
