notification strings as static strings, not in +initialize.
(thread_id_2_nsthread): Renamed from THREAD_LIST. Keep the collection
of NSThread's as a maptable, not a NSArray that takes linear time to
search!
(thread_lock): Renamed from THREAD_LIST_LOCK.
(entered_multi_threaded_state): Renamed from ENTERED_MULTI-THREADED_STATE.
([NSThread +initialize]): Don't initialize notification strings here.
Don't autorelease the lock!
([NSThread -init]): Initialize _thread_autorelease_pool. Set our
thread data to self, for easy, efficient access to this NSThread
object later. Put ourselves in the thread collection here, not in
+detach...
([NSThread +currentThread]): This will be called often and needs to be
fast. Reimplemented so we don't have to acquire a lock and step
through an NSArray of threads; instead, just look ourselves up with
the objc_thread_get_data(), and furthermore, no lock required.
([NSThread +detachNewThreadSelector:toTarget:withObject:]): Avoid race
condition, don't create new NSThread object here.
([NSThread +sleepUntilDate:]): Call -notImplemented:.
([NSThread +exit]): Properly post NSThreadExiting notification, making
sure not to hold the lock while we do so. Get the NSThread object
efficiently.
([NSThread -threadId]): Removed unnecessary private method.
([NSThread -setThreadId]): Likewise.
