Most request processing hooks are passed the request_rec which has a
pool with request lifetime.  Similar for connection-level hooks and
conn_rec.

While parsing directives, you have pools passed on the cmd_* structure
which are either temporary or very long-lived.

Finally, you can create & destroy a new pool if you are in some very weird code.

Could you elaborate on the context?
