Log Message:
	In io_callback() service writes before reads.  That way, if both
	SUDO_EV_READ and SUDO_EV_WRITE are set and read() returns 0 (EOF)
	we don't close the fd before the write() is performed.

	If the write() returns EPIPE, ENXIO, EIO or EBADF, clear SUDO_EV_READ
	before we close the fd to avoid calling read() on a closed fd.
