You can use

PersistenceBroker.clearCache();
to evict the whole cache

PersistenceBroker.serviceObjectCache().remove(Identity oid);
remove a specific object

Take care that all insert/update/delete operations are performed within 
a running transaction, else the cache will be corrupted.
Take care that mandragora use your current PB instance or get a new PB 
instance after using mandragora (to avoid session cache issues).

All "delete by query" stuff (PB.deleteByQuery) doesn't synchronize with 
the cache.
