Don't worry about uname. What you've shown indicates we're using the same Perl version but completely different OSes: I'm using Mac OS X; you're using MS Windows.

Be aware how the number of iterations grows with respect to $rep: 4 = 4; 5 = 10; 10 = 120; 20 = 1140; 100 = 161700; and so on.

You didn't indicate how the code changes affected the leaks. My tests still show no leaks — I'm unable to reproduce your problem.

I can't see any leak-related isues with %haystack; although, that doesn't mean there aren't any. I do note that you're populating @wants twice with what appears to be the same data: 

my @wants = grep { is_approximately_an_integer( @$_ ) } values %haysta
+ck;

# intervening comments here only

@wants = grep { is_approximately_an_integer( @{$haystack{$_}} ) } keys
+ %haystack;

Obviously, you only want one of those. Also, if %haystack is only used to populate @wants (you don't show any other usage in your code), consider whether the is_approximately_an_integer() filter might be better placed in the innermost loop (possibly doing away with %haystack altogether).
