Log Message:
	Ignore SIGTTIN and SIGTTOU in main sudo process when I/O logging.
	It is better to receive EIO from read()/write() than to be suspended
	when we don't expect it.  Fixes a problem when our terminal is
	revoked which can happen when, e.g. our sshd is killed unceremoniously.
	Also, only change the value of "alive" from true to false, never
	from false to true.  It is possible for us to receive notification
	of the child having stopped after it is already dead.  This does
	not mean it has risen from the grave.
