Modified files:
sys/kern : kern_exit.c
Log message:
Prevent exit status from being clobbered on thread exit.
Ensure that EXIT_NORMAL only runs once by guarding it with PS_EXITING.
It was previously possible for EXIT_NORMAL to be run twice, depending on
which thread called exit() and the order in which the threads were torn
down. This is due to the P_HASSIBLING() check triggering the last thread
to run EXIT_NORMAL, even though it may have already been run via an exit()
call.
