// netbsdMstart0 is the function call that starts executing a newly
// created thread. On NetBSD, a new thread inherits the signal stack
// of the creating thread. That confuses minit, so we remove that
// signal stack here before calling the regular mstart. It's a bit
// baroque to remove a signal stack here only to add one in minit, but
// it's a simple change that keeps NetBSD working like other OS's.
// At this point all signals are blocked, so there is no race.
