This class allows a mechanism to greatly reduce the syscall and IPC overhead when checking whether a caller on the system bus message is allowed to do a specific action. In a nutshell, this class caches PolKitCaller objects and a) updates them when ConsoleKit emits ActivityChanged signals; and b) evicts such objects from the cache when the caller drops off the bus. There's also an example, in examples/tracker-example/ that shows how to use this. This example is referenced in the API docs too.
