* win32-threads.cc:
        (_Jv_CondWait, _Jv_CondNotify, _Jv_CondNotifyAll): Corrected
        wait() algorithm to make it safe.
        (ensure_condvar_initialized, _Jv_CondInit, _Jv_CondDestroy):
        Added lazy creation of Win32 Events for better performance
        (really_start): This now uses GC_CreateThread so boehm-gc
        knows about new threads even when statically linked.
