Yep, sorry about that.  I was working off the old email exchange between 
you and Chandana and had not noticed that 835 had been created.
I'll merge 'em.  But a couple of questions ...

1. should we use the perl probe (nothing extra to install) or nc(1) (may 
or may not be installed)?
2. I don't know enough about "slabs" for memcache to know if the stats 
from "stats slabs" and "stats items" are genuinely interesting ... the 
PMDA does not currently expose this AFAICT.
