possible fix to Cache::Memcached (also, large object support q)

When calling flush_all() with Cache::Memcached 1.18, a warning happens:

   Use of uninitialized value in send at
   /usr/local/share/perl/5.8.7/Cache/Memcached.pm line 339

This appears to be because flush_all() calls run_command(), which then
calls _write_and_read() _twice_ instead of once. The 'last' in
run_command() doesn't trigger because flush_all returns OK, not END or
ERROR (at least that's the case in 1.1.1{2,3}).

A patch is attached. Is it correct?

While I'm here: Does the newer stuff in 1.2.0 offer large object
support similar to the kind provided by the patch at:


If so, what's the magic?
