That all depends on where the original array declaration is. If it's in
some block whose scope is limited to the request, it'll get properly
cleaned up. If it's got file-scope or something undesirable like that,
you'll have to clean it up manually - or better, just fix its scoping.
BTW, I usually prefer '@array=();' to 'undef @array;', because I like to
let Perl handle the memory allocation/deallocation. If memory is tight
though, then I suppose you'll do what you have to do.
