// Specifically, it tests a scenerio wherein a C
// thread is calling into Go, creating a goroutine in
// a syscall (in the tracer's model). Because the actual
// m can be reused, it's possible for that m to have never
// had its P (in _Psyscall) stolen if the runtime doesn't
// model the scenario correctly. Make sure we reject such
// traces.
