Compile memcached as a 64bit binary and you should be able to use as
much memory as you want (I have tested with up to 30Gb)... Please note
that memcached use more memory than the memory specified with -m (for
internal buffers etc), and you should leave memory for the os and
other processes. The last thing you want is that your server is paging
in and out memory pages..

If you do a lot of large multi-gets, you'll use more ram than otherwise.
Future releases will probably track this memory more closely? It's not
hard to do.
