The

state = 0x0 = STATES_READY
Wait.flags = 0x02 = THREAD_WAIT_STATE_BLOCKED

state = 0x0 = STATES_READY
Wait.flags = 0x04 = THREAD_WAIT_STATE_READY_AGAIN

after a call to _Thread_Timeout(),

Ok, good.

I still think it would be worth to try the latest RTEMS master just to 
make sure we don't search a bug which is already fixed. Also RTEMS 5 as 
more assertions in the debug configuration.
