* src/sched/sched.cxx (thread_entry): Fixed a bug which could cause a thread to be started with a non-zero scheduler lock. The previous code only decremented it by 1 so if the previous thread was executing with the lock > 1 the thread ended up with a non-zero lock. This is fixed by decrementing the lock in a loop until it reaches zero. * src/common/thread.cxx (idle_thread_main): Added an assert for a non-zero scheduler lock.
