Hi,everyone!
as you know,scheduler::lock()/unlock() can't settle down race conditions for mutithread accessing scheduler's data structure,such as threadQueue.
for example, current thread was accessing thread queue(add_thread_to_list())with lock() taking when a interrup occurs,this interrupt also accessing threadqueue,so race condition for thread queue occurs,because lock(0/unlock()simply
do "schedLock++/--",it can't resolve this BIG problem!
Right?
