Large memory support?

[Jeremy]

Using memcached now on a x86_64 with 16gigs of memory.  It seems memcached
is topping out at about 2gigs.  Does memcached have large memory support?
This is my running process:

memcached -d -p 11211 -u nobody -c 1024 -m 14336

I'd like to use up to 14gigs.

  PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND
22371 nobody    15   0 2074m 2.0g  272 S    3 12.3 201:53.39 memcached

And it's not growing beyond 2gig.

Thanks
