Name: Expire's type overflow when showing tuples at bad moment.
Status: Tested under Linux 2.6.6 uml patched.
Signed-off-by: Samuel Jean <sjean@cookinglinux.org>

When garbage collector runs slow enough, we have a chance to print
expired tuples before they get freed. We see weird expiry time.

Not sure if I needed 'now' reference so I didn't took chance.
