bugfix #144: Do not free kstack when the main thread exits #146

Closed wyfcyx closed 6 months ago

wyfcyx commented 6 months ago

When the main thread exits, we do not free its kstack since it is still being used before sched. It will be freed when the whole process is reaped by the parent process.
