New return codes on interrupt or non-ownership + of mutex. + (_Jv_CondNotify): Ditto. + (_Jv_CondNotifyAll): Ditto. + (_Jv_ThreadInterrupt): Set thread interrupt flag directly. Interrupt + the target thread by signaling its wait condition. + (_Jv_ThreadInitData): Set `thread_obj' in the thread data struct, + not the starter struct. Initialize wait_mutex and wait_cond. + (_Jv_MutexLock): New recursive mutex implementation. Moved from + posix-threads.h. + (_Jv_MutexUnlock): Ditto. + (really_start): Set info->data->thread from pthread_self() to work + around a race condition. Destroy wait_mutex and wait_cond when run() + returns. + * java/lang/Thread.java: (isInterrupted_): Renamed to overloaded + `isInterrupted(boolean)'. Clear interrupted flag if clear_flag is + set. + startable_flag: New private field. + (Thread): Initialize `startable_flag'. + (toString): Check for null thread group. + * java/lang/natThread.cc: (struct natThread): New fields + `join_mutex', `join_cond'. Removed fields `joiner', `next'. + (class locker): Removed. + (initialize_native): Initialize `join_cond' and `join_mutex'. + (interrupt): Now just calls _Jv_ThreadInterrupt(). + (join): Simplified. Just wait on the target thread's join condition. + (finish_): Remove join list code. Unset thread group. Signal + potential joiners by notifying the dying threads join_cond. + (start): Check for illegal restarts. + * java/lang/natObject.cc: Check for return value of _Jv_CondWait and + act appropriatly. + * include/posix-threads.h: Remove all HAVE_RECURSIVE_MUTEX related + #defines and #ifdefs. + (struct _Jv_Thread_t): New fields `thread_obj', `wait_cond', + `wait_mutex', `next'. + (struct _Jv_ConditionVariable_t): Define as a struct instead of + directly mapping to pthread_cond_t. + (struct _Jv_Mutex_t): New recursive implementation. + (_Jv_PthreadCheckMonitor): Reimplemented.

Add a FIXME about this. + (_Jv_CondNotifyAll): Ditto. + * win32-threads.cc: (_Jv_CondWait): Return 0 on a timeout. Guess + _JV_NOT_OWNER on other errors.
