So, you can actually execute that piece of code to dl a large file (~100MB+) and have it copied directly to a file, without using a portion of memory directly proportional to file's size?
If that is the case, then I most definitely must be missing something. Can you spot something wrong with my code?

PS: Didnt know 'Devel::VersionDump'; thanks for the input.

    I did 38M/135M and , the memory never grew past 10M. For server (never past 12M) I used

     plackup -l localhost:80 -e " use Plack::App::Directory; my $app = Plack::App::Directory->new({ root => q[.] })->to_app; "

    Nope, I don't see any mistakes but on linux (BREWED) makes me think maybe you're using a fudgy malloc? Kinda unlikely but I've seen folks complain about it :) I'm on win32 so you probably can't compare my Config:)

    $ perl "-V:.{0,}alloc.{0,}" d_attribute_malloc='undef'; d_malloc_good_size='undef'; d_malloc_size='undef'; d_mymalloc='undef'; i_malloc='define'; i_mallocmalloc='undef'; mallocobj='malloc.o'; mallocsrc='malloc.c'; malloctype='void *'; usemallocwrap='define'; usemymalloc='n';
