- add PTHREAD_PID_DEBUG which prints the pid before each debuglog line - output thread returned in pthread__next - add asserts in pthread__sched akin to asserts in pthread__sched_bulk: check if scheduled thread is at front/end of queue - pthread__upcall: output event/interrupted LWP count instead of LWPid of the first event/interrupted LWP (since unblock upcalls can have multiple event LWPs). - pthread__find_interrupted: output LWPid here
