just to improve readability, maybe they can be
num_clients_ and num_deleted_clients or
can be even xxx_for_current_origin_?

Done.  Chose num_deleted_clients.

style nit: declaration order (from what I was told before)
* Typedefs and Enums
* Constants (static const data members)
* Constructors
* Destructor
* Methods, including static methods
* Data Members (except static const data members)

[Dai Mikurube (NOT FULLTIME), 2011/05/12 02:45:50]

Thanks. Re-ordered.
