In a few places we always end up mapping the pool object with the FORCE constraint(to prevent hitting -EBUSY) which will destroy the cached mapping if it has a different type. As a simple first step, make the mapping type part of the pool interface, where the behaviour is to only give out pool objects which match the requested mapping type.
