This is required by traceThreadDestroy, though it's not strictly necessary in this case. The requirement to hold sched.lock comes from the assumption that traceThreadDestroy is getting called when the thread leaves the tracer's view, but in this case the extra m that dropm is dropping never leaves the allm list. Nevertheless, traceThreadDestroy requires it just as a safety measure, and that's reasonable. dropm is generally rare on pthread platforms, so the extra lock acquire over this short critical section (and only when tracing is enabled) is fine.
