We do it the same way you do -- when we are not using Performer -- and
it seems to me like the right way. But if you are using Performer, it
is simpler to derive your class from pfObject or pfMemory, as you say.
Note, however, that the default new operator for a pfMemory does NOT
allocate from shared memory (you have to specify the arena), and that
you cannot allocate a pfObject until you have called pfConfig() (I seem
to recall).
