We have 'File' which associates a name with a file and will be used to offer an interface for the application. Posix 'Filehandles' which are managed in a 'Filehandlecache' to utilize a limited number of fd's at optimum. Internally we use 'Filedescriptor's which manage files, mapping and all kinds of metadata. Filedescriptors weak referenced by a registry and freed when the last user vanishes.
