Log Message:
	If we receive a signal from the command we executed, do not forward
	it back to the command.  This fixes a problem with BSD-derived
	versions of the reboot command which send SIGTERM to all other
	processes, including the sudo process.  Sudo would then deliver
	SIGTERM to reboot which would die before calling the reboot() system
	call, effectively leaving the system in single user mode.
