=========================== BIG THINGS TO DO ==================================

- Distributed Objects
- Unicode support in NSString


========================== SMALL THINGS TO DO =================================

- NSException thread-safe
- finish NSFileManager
- port to Solaris and HP-UX (NSInvocation and NSMethodSignature)
  (what about OSF/1 and Ultrix?)
- finish NSRunLoop and NSTimer
- serializer/deserializer
- change NSPosixFileDescriptor to NSFileHandle
- change NSZone from class to struct

============================ general checks ===================================

(The following does not necessary mean they are missing ;-). These should
remind implementors what do they have to check for. )

- implement `copyWithZone:' and `mutableCopyWithZone:' for all classes

- implement `encodeWithCoder:' and `initWithCoder:' for all classes

- implement meaningful `description', `descriptionWithIndent:' or
`stringRepresentation'

- revise `hash' `isEqual:' and `compare:' methods for all containers so that
isEqual/compare/hash shoud be consistent

- check that all `dealloc' calls [super dealloc] to release memory

- check that calls to [super init] are done before *any* ivar is set

- check imutable `copyWithZone:' for containers so that it performs a deep
copy, making all its content imutable

- check mutable `mutableCopyWithZone:' for containers so that it performs a
shallow copy, making all its content imutable

- thread-safe notes (comment with `// THREAD') where we access global variables
