[Expectperl-announce] New release: Expect-1.18

[Roland G. <RGi...@cp...>]

Fixed hanging spawn on AIX (and others).

Closing the pty slave in the parent would hang if the spawned child
already wrote something to the pty. I added another sync via pipe to
make sure that the parent first closes the slave before the child
execs.
