| |
Dear Ingo,
CLONE_CLEARTID was created so that a thread can notify its partner threads that its stack may by freed or reused. It is needed because the stack isn't free until the exit() system call begins.
One question has been bothering me for a while: what about the thread group leader's stack? These days, isn't it the case that the group leader is supposed to be equivalent to the other threads? If so, how does it exit and release its own stack -- or do we understand that the group leader, as a one-off exception, has to block signals before exiting?
