That'll be because you got a different process next time.

If this is just a matter of efficiency, then what you're doing
is probably already right.  Each process will grow its own cache,
which is less efficient than you hoped, but only by O(1).

Note that you shouldn't use pconf when processing a request.
Your module can create its own private pool.  You'll still
need to take care with memory use and thread-safety when
using it.
